Harper's Island

Characters gather on the ferry to Harper's Island for the wedding of Henry Dunn and Trish Wellington. Trish's cousin, Ben Wellington, is missing, but they decide to go anyway. Unbeknownst to those on board, Ben has been tied to the drive shaft of the boat and goes head first into the propeller when the engine starts. On the voyage to the Island, Henry and his life-long best friend, Abby Mills, discuss her concerns about the trip. Her mother was one of the victims John Wakefield murdered seven years earlier. Also among the wedding guests is Henry's Uncle Marty who is secretly traveling with $250,000 and a gun.

The party arrives at The Candlewick Inn and Abby reacquaints herself with her old surroundings. Hunter Jennings, Trish's ex-boyfriend, arrives in secret on the Island per Mr. Wellington's summons, intending to break up Trish's marriage to Henry. Uncle Marty confronts Mr. Wellington about these plans and his treatment of Henry. While out for a walk later, Marty falls through a footbridge and is cut in half by an unknown killer. Once the evening winds down, Abby returns to her room to find a newspaper article taped to her bathroom mirror about her mother's murder at the hands of John Wakefield.

While out for a run, Abby is startled by her ex-boyfriend, Jimmy, and another Harper's Island local, Shane, who are out hunting deer. Trish meets with Hunter again and reaffirms her intention of marrying Henry. Meanwhile, the Reverend Fain is caught in a rope trap and decapitated in the woods by an unknown assassin.

A festive scavenger hunt begins at the Candlewick and Abby catches up with Kelly, another local whose mother was murdered by John Wakefield. Trish confides in Lucy that Hunter is on the island and that she doesn't know what to do. In an effort to thwart Sully's advances on Chloe, Cal ventures out alone in the woods to find them and he is caught in a rope trap. Sully comes upon Cal, declares he is unable to free him and tells Cal that he will be back with help, but neglects to do so. Later that evening Chloe expresses her concern that Cal is still missing and Sully leads them to his whereabouts. They find him, still dangling upside down but very much alive.

Trying to keep the peace between Shane and J.D., Henry extends an invitation to Jimmy and Shane to attend the beach party that evening. However, the truce is short-lived when Henry arrives back at his room to discover a deer's head in his bath-tub. Nikki arrives at Kelly's house to pick her up for the beach party but finds her dead, hanging from the rafters. Shane arrives at the party and gets punched by Henry for the "deer in the bathtub" prank. During their altercation, Lucy's dog scampers off into the woods. Running after her, Lucy falls into a pit. Her screams for help are drowned out as the murderer sets her on fire.

Sheriff Mills informs Abby that Kelly committed suicide but she refuses to believe it. When Abby breaks the news of her death to J.D., he does not react; leaving Abby concerned and suspicious because she saw him with Kelly on the night that she died. When Shane hears the news of Kelly's death, he immediately suspects J.D. and sets out for revenge. As J.D walks along a country road, Shane runs him down with his pick-up truck and abducts him. Meanwhile; Henry discovers that Trish's ex-boyfriend, Hunter Jennings, is staying at a nearby hotel. Forging Hunter's signature, Henry sends Trish a note to meet him at a room in the Candlewick Inn. Trish approaches the door to the hotel room, but she hesitates and leaves. Inside the hotel room; Henry smiles to himself at this sign that Trish has chosen him over Hunter.

Knowing of the bad blood between Shane and J.D., Abby goes to Shane's house and finds J.D. held captive in his barn. Abby tries to persuade the crazed Shane that Kelly died, not by suicide, but was murdered at the hands of John Wakefield. Sheriff Mills comes upon them. He saves Abby and J.D, and arrests Shane. That evening at dinner, Trish and Henry present a loving, unified front to her father. At this sign that he has lost Trish to Henry, Hunter blackmails Mr. Wellington. He promises not to tell Trish that her father brought him to the island to break up the engagement if Mr. Wellington pays him $50,000. Mr. Wellington agrees and Hunter leaves the Island with his money. As he sails away from Harper's Island, Hunter is killed by a rigged shotgun on the boat.

Driving into town, Jimmy and Abby reminisce and begin to rekindle their relationship. Once in town, Abby visits the local newspaper, Harper's Globe, to pick up a childhood picture of Trish and Henry as a wedding gift. While waiting, Abby is unsettled by the discovery of old editions featuring stories about the Wakefield murders. Robin Matthews tells her that someone was inquiring about them, but the person never came to pick them up. The day of the bachelor/bachelorette parties arrives. While out fishing, Henry and his groomsmen come across Hunter's boat. They discover his body and the bag of money with the gun. They deliberate whether or not to report it. Then Malcolm rashly sinks the boat instead, taking the money and gun, instigating the other bachelors to reluctantly follow suit. When they return to the Candlewick Inn, the men agree to conceal the $250,000 that they misappropriated and deal with it after the wedding.

When two armed men in suits come by the bar at the Inn, the groomsmen decide to hide the money immediately. Booth heads out into the woods to bury the money and Malcolm follows him. Booth, accidentally shoots himself in the leg and bleeds to death despite Malcolm's desperate attempts at care. At the bachelor party, the friends are relieved to discover the two suited men are merely security guards for the stripper. Malcolm arrives and lies about seeing Booth. Back in his hotel room, Malcolm hides the bag of money and mourns the loss of his friend. Trish's afternoon tea is ruined when she discovers that her Mother's china has been vandalized. At the bachelorette party, a tarot reader warns Abby that she must leave the Island. Freaked out with this encounter, Abby goes to Jimmy's house and stays the night. Upset over the loss of her Mother's china, a drunk Trish falls into the hotel swimming pool and becomes trapped when the pool cover closes. Trish loses consciousness and begins to drown; but her brother-in-law, Richard, arrives and rescues her.

It's the day before the wedding. Trish stresses out over all that still needs to be done. Henry tells Trish to take the morning off and spend time with her father while he handles all the final preparations. Henry is overwhelmed with all the wedding details and finds a decaying animal carcass on the altar. Deducing that J.D. is responsible, Henry confronts him and tells him that he never wants to see him again. J.D. foreshadows that he has "one more surprise" for Henry. Meanwhile, Sheriff Mills and his deputy investigate the disappearance of Reverend Fain. At his home, they find unopened mail and unheard voice messages. Their search ends when they dredge up his dismembered body from water by fishing line. Concurrently, Abby visits her father's house and discovers newspaper articles about John Wakefield. She looks them over and reasons that the Sheriff thinks Wakefield is still alive.

On a bike ride in the woods, Trish and her father trip a swinging log booby trap that knocks them off their bikes. They start walking back towards the Candlewick Inn, toughing out their injuries. They come upon a figure in the woods and ask for help. In response, the figure sets a German Shepherd on them. They evade the dog and then kill it in a struggle, then escape and make their way back to the Candlewick Inn. The wedding rehearsal begins. At the altar, Henry stands with Trish and Mr. Wellington. Abby is asked to turn off the lights. As she does, a head spade inserted into the chandelier above Henry, Trish, and Thomas drops from the fixture and pierces Wellington's skull.

The Sheriff commences his investigation into Mr. Wellington's murder and soon deduces that someone wanted him, specifically, dead. Henry tells Abby about J.D.'s possible involvement in Wellington's murder. J.D. denies having anything to do with the murder and restates the idea that John Wakefield is still alive. J.D leads Abby into the woods to reveal the body of Uncle Marty tied up in a tree. They find Henry and break the news of Uncle Marty's murder and their belief that John Wakefield could be involved in it and other recent deaths. Abby takes Henry to her father's attic to show the research on Wakefield. Together; the three of them confront the Sheriff, who continues to reassure them that Wakefield is dead. J.D does not believe him and decides to dig up Wakefield's grave, but the Sheriff locks him in the pantry.

As the Sheriff questions the rest of the wedding party, Abby and Henry dig up Wakefield's grave. They discover a skeleton in the coffin shortly after the Sheriff arrives to see. Back at the Inn, Madison lets J.D. out of the pantry. J.D runs through the woods and enters the cabin of the mysterious, scarred character. Sheriff Mills starts to suspect Richard Allen (Shea's husband and Madison's father) for the murders. The lawman asks Richard about his relationship with Thomas Wellington and his affair with Katherine Wellington. Richard admits that he hated Wellington and the affair was his way of humiliating his father-in-law. Afterward, knowing that he is the prime suspect in the murder, Richard calls his lawyer. While is on the phone, Richard gets harpooned through the chest.

After Abby, J.D., and Henry examine the clues in the sheriff's attic, the guests begin to form a theory about the slayings. The atmosphere at the Candlewick Inn darkens when the Sheriff begins conducting searches of everyone's rooms in the wake of Thomas Wellington's death, and finds uncle Marty's phone in J.D.'s bag, claims him to be the killer and arrests him.

In a series of flashbacks, it is shown what happened with the Wakefield murders 7 years earlier. Abby goes to her father's house to collect some things when she is startled by the mysterious, scarred character, who she recognizes as Cole Harkin, who tells her that her father can not be trusted and tells her to ask her father why Wakefield came to the island. When she does, Sheriff Mills explain that Abby's mother used to date Wakefield until he got violent with her, and she ran away to the island to get away from him. That is how they had met. Wakefield tracked her to get her back, but Sheriff Mills ordered his deputies to teach Wakefield a lesson. They beat him up, but Wakefield fought back, leaving one of the deputies badly hurt. Rather than charge Wakefield for assault, he has him arrested for an attempted murder of a police officer. Wakefield was let out prison for good behaviour and came back for revenge.

Meanwhile, Malcolm stresses over the possibility that police will find the bag of cash he's concealing. He evades discovery until Sully and Danny come snooping. After both groomsmen inflict guilt over Booth's death because of Malcolm's desperation for cash, Malcolm goes to the basement of the Candlewick Inn to burn the money in the garbage incinerator. While watching some of the money burn, Malcolm is savagely decapitated by an unseen murderer. The killer throws Malcolm's body parts into the flames. Later, while worrying about her father's disappearance, Madison receives a mysterious missive. She goes to a meeting place in the Candlewick Inn, specified in the letter. The door of the room slams shut, as if to trap Madison inside.

The wedding party are preparing to leave Harper's Island. At the police station Sheriff Mills questions J.D. about Cole Harkin. J.D. says that Cole is staying in a cabin in the woods. Sheriff Mills heads off to see Cole.

Meanwhile Shea announces that Madison is missing and everybody comes to help find her. Back at the police station, J.D. and Shane fight in the cells where they are locked up. Deputy Garrett attempts to break up the fight when suddenly two gun shots ring out - the first kills Garrett and the second destroys the shortwave radio. J.D. manages to escape, leaving Shane locked in the cells. While looking for Madison, the wedding party find Malcolm's skull in the incinerator and Richard Allen's dead body. Abby gets a phone call from Madison's phone, saying if anyone leaves the island Madison will die. At that point power to the whole island and cellphone reception stops working.

In the woods, Sheriff Mills tries to find Cole Harkin but instead his leg is badly cut in a booby trap. Cole shows up and helps him to the cabin. At the Candlewick Inn, Maggie gives the Inn's shotguns to everybody. Jimmy arrives to tell everyone the boat has left without them. Abby and Jimmy head over to the police station to use the shortwave radio, but find it broken. Instead they find Shane in the cell and he tells them that Sheriff Mills went to the woods.

In the cabin, Cole Harkin tells Sheriff Mills that he has found Wakefield's journal and goes off to get help. Then an arrow flies out, pinning Cole to the cabin and killing him. He drops the journal and a lantern, starting a fire. Abby and Jimmy rescue Sheriff Mills and the journal from the fire. Henry and Danny manage to get the generator going and discover that half of the wedding party is missing. Sully, Beth, Cal and Chloe try to escape from the island even after they have been told that Madison will be killed if anyone leaves. Sheriff Mills tries to get Abby and Jimmy off the island but instead runs into the others as they try to find J.D. Abby finds J.D. with his stomach cut open, and before he dies he says the killings are all about Abby.

After reading John Wakefield's journal, Abby finds out she could be his daughter. After over-hearing this information, Shane tells everyone still staying in the Candlewick Inn that he believes Abby is the murderer, causing the party to start turning on her and each other. This tension causes Abby to realize that she is at the center of the killings. After denying Abby a place inside the Inn, Shane is attacked by Henry, who is only stopped when the group pulls him off. Meanwhile, Cal and Chloe are attending to Sheriff Mills' leg injury. Chloe gets turned on when Cal saves his life and they sleep together in a separate room. Cal wakes up to discover that the Sheriff is missing.

Moments after the fight, Sully realizes that Beth is missing. He and Danny search for her and start following a trail of blood, which leads them to a tunnel system. Danny finds Beth's body in one of the tunnels as Abby gets trapped in a separate tunnel while also attempting to locate Beth. After finding her safe in a room, Abby and Madison attempt to find their way out of the tunnels, only to be found by Trish and Shea, who were driving to see the psychic. Meanwhile, Shane discovers someone has killed Katherine by stabbing garden shears through the back of the couch on which she had been sitting.

Madison leads the group to believe that the Sheriff is the man who kidnapped her, causing them to suspect that he is in fact the murderer. The group decides to leave the island on Jimmy's boat, but after seeing the dead cops, Shane calls for everyone to get off the dock. Moments later, the dock explodes, along with all the boats. The group takes refuge at The Cannery, where Nikki shows up in fear. Later, Maggie decides to leave and appears to have gone home, but she is later hung from the Cannery sign in front of the group.

After creating a small diversion, Cal and Sully are able to take Nikki's car to get to Cal's sailboat, but not without consequences. Hours later, the Sheriff's truck delivers the gang an unconscious Jimmy. This prompts Abby to go back to the Candlewick Inn, where she finds her father. She blames him for the murders, but he tells her it has been Wakefield all this time. After a few revealing secrets and twists, Abby witnesses her father die at the hands of Wakefield, who confronts her.

It is revealed that Wakefield has been "friends" with Madison since the day everyone arrived on the island. While at The Cannery, Madison informs everyone "Mommy, he's here!". Nikki grabs for a gun, but is too slow and Wakefield kills her. Shane distracts Wakefield while the girls run to safety. Danny, Abby, and Henry make their way back to The Cannery to find a dead Shane and Nikki and the girls missing. Trish, Shea, Chloe, and Madison end up at Sheriff Mills' house, hiding in the attic. After hearing bells from the church, the girls and the group at The Cannery make their way over, each thinking someone from the other group was ringing it. They meet up and realize that Jimmy is missing and Deputy Lillis is dead.

Moments later, Sully and Cal enter the church, while Wakefield sneaks in and grabs Chloe. Moments later, Jimmy enters the church after hearing the bells. The group decides to split up to block off the exits to the tunnels Wakefield is using to get around the island. Danny and Sully encounter Wakefield and decide to enter the tunnels to help their friends. In the woods, Cal finds and rescues Chloe while Abby and Henry are chasing Wakefield. Moments after rescuing Chloe, Cal proposes to her. Wakefield shows up and kills Cal, then throws him off the bridge. Chloe tells Wakefield "You can't have me," and jumps to her death. It is revealed that the Sheriff thought Wakefield had an accomplice, and Shea thinks it is Jimmy.

After witnessing the deaths of Cal and Chloe, Henry and Abby are off to find Wakefield. Danny acts as bait to lure Wakefield out, but when it comes to killing him, Abby can't do it. Instead, she knocks him out and they carry him to the police station where they lock him up. Henry goes to find Trish and Jimmy, but they have left the car.

While at the station, Shea tells the group that Sheriff Mills suspected Jimmy of being a Wakefield copycat, causing the group to analyze Jimmy's behavior and brushes with death. Jimmy comes to the station, seemingly upset that Trish has fallen off a cliff and is stuck. Wakefield reveals to Abby that she is in fact the reason behind the killings, and that he really loved her mother. He reveals that Abby's mother gave Wakefield's son up for adoption, but Wakefield found him. Meanwhile, Jimmy, Henry, Abby, and Sully go off to rescue Trish, who they find unharmed. Trish found a radio, and with the help of Sully and Jimmy, was able to contact the coast guard who state they are sending help.

Back at the station, Shea, Madison, and Danny are playing games when Wakefield escapes from his cell and kills Danny, who stayed behind to allow Shea and Madison time to escape. While wandering through the woods, Jimmy and Abby come upon Madison and Shea. They send Madison and Shea to safety and go find Trish and Henry. They arrive at the Inn to find that Wakefield has already been there and Trish and Henry are missing. Trish, who is on the run from Wakefield, stumbles upon Henry. Her happiness turns to horror when Henry reveals that he is Wakefield's accomplice. After a struggle, Henry kills his fiance. The audience is also informed that Henry is Wakefield's biological son.

Starting with a flashback, Henry and Abby are shown to be best friends. His parents come to pick him up, and through glances, the audience is told that Abby's mother and Henry's adoptive mother know what happened. Henry and Abby share a secret before he goes back home to Tacoma. Wakefield and Henry are discussing their overall plan when they hear Abby approaching, and they leave Trish's body in the woods. Shea and Madison make it to the boat house where Sully learns Wakefield has escaped. Abby and Jimmy find Trish's body, and decide to leave her there to find Henry. Meanwhile, Sully sends Shea and Madison off towards Seattle on a small boat, while Henry takes Sully into the woods to "find Trish." There, Henry tells Sully everything, but he doesn't believe him at first. Eventually he tries to shoot Henry, but Henry removed the bullets at the boathouse. Henry and his father kill Sully while Henry tells him "you never should have dogged Trish," leading the audience to believe that Henry cared for Trish.

Abby and Jimmy then come across Henry, who is alone. He doesn't seem to believe them when they tell him Trish is dead. Instead, he runs to the church where Trish's body is. There Abby, Jimmy, and Henry are found by Wakefield. Wakefield attacks Jimmy, who yells for Abby to run. When she leaves the church, Wakefield yells at Henry that Abby is escaping. Jimmy connects the dots, and fights off Wakefield while Henry runs to find Abby. Henry catches up to Abby and instead of killing her, kills Wakefield, who is surprised.

Abby pieces everything together and tries to run from Henry, but she is knocked unconscious. The scene shifts to Shea and Madison, who are informed that they are the only survivors, other than a handful of locals. The scene shifts yet again to Abby, who wakes up in a house. Downstairs, she finds Henry. He explains that they were meant to be together, and that no one knows they are half-siblings, which makes everything okay. Attempting to escape, she finds Jimmy, who is tied up. Henry has him sign a full confession in exchange for keeping Abby safe. Henry gets jealous when Abby admits she loves Jimmy and he slaps her. While on the floor, Abby stabs Henry in the foot. Having slipped Jimmy tools to help him unlock himself, Abby leads Henry on a chase, where she tells him that she doesn't want or love him. Distraught, he doesn't notice Jimmy coming up on him, and together, Henry and Jimmy go off a cliff. While checking on Jimmy, Henry walks up behind Abby and she stabs him. His last words to her are "Abby, I love you." Abby and Jimmy make it off the island safely.
