Quantum Leap (season 2)

Sam leaps into stuntman Chad Stone (Kevin Light) on the set of a disco-themed disaster film. Sam must prevent his host's brother, Chris (Kris Kamm), from being the victim of a freak stunt accident while also steering him toward a career in music. To do so, Sam must prevent the boy's father, stunt coordinator Ray (Michael Greene), from keeping Chris away from music.

Sam leaps into Charles Lee MacKenzie (Bill Arnold), a US Navy aviation machinist's mate returning to the family farm in Ohio with Machiko (Leila Lee Olsen), his Japanese bride, after being stationed in Japan for two years. Sam must help his host's mother (K Callan) accept his new bride, fend off the advances of his ex-girlfriend (Elena Stiteler), and fight off a potentially deadly response from Rusty (Patrick Massett), a racist veteran of World War II.

Sam leaps into a woman for the first time, a stunning blonde named Samantha Stormer (played by LaReine Chabut). He must prevent Gloria (Jean Sagal), his host's roommate, from killing herself when her married boyfriend, Sam's host's boss Buddy (John Calvin), refuses to divorce his wife. Sam also has to deal with sexual harassment from Buddy, an auto executive who makes business decisions convinced "the good times are here to stay", whereas Sam drops hints that the American auto industry is headed for a rude awakening.

Sam leaps into Carnegie Hall as Andrew Ross (Billy Burdin), a blind pianist. His time in New York City overlaps with The Beatles' Ed Sullivan appearance, and a serial killer active in Central Park. His apartment neighbour, NYPD Officer Peter O'Shannon (Kevin Skousen), is pulling double duty with crowd control for the mobs of screaming Beatlemaniacs. Sam must save his host's girlfriend, Michelle Stevens (Cynthia Bain), from being strangled by the killer, while also convincing Michelle's bitter single-mother (Jennifer Rhodes) that the young couple are right for each other.

Sam leaps into Howlin' Chick Howell (Douglas Ibold), a Good Morning, Vietnam-type DJ of a radio station in a city where local newspaperman Fred Beaman (Richard McKenzie) convinces the city council to ban rock & roll. Sam and station owner Rachel Porter (Patricia Richardson) barricade themselves in the station and thwart several attempts by the authorities to take the station off the air.

Sam is David Basch (John J. Reiner), a rabbi whose brother's family is still suffering from the death of their son in a plane crash. When Sam must perform a bat mitzvah, Al talks him through it, revealing that his third wife was Jewish. Sam must help his host's brother, Joe (James Sutorius), stop blaming his wife, Irene (Terri Hanauer), for their son's death – which is destined to drive her into an affair with Bert Glasserman (Russ Tamblyn), a sleazy author who is secretly using her (and other married women) to write a book. After saving their marriage, Sam does not leap until he makes Joe and Irene realize how, in their grief, they have shut out their remaining child, 13-year-old Karen (Lindsay Fisher).

Sam is Ray Hutton (Michael Carl), the understudy to alcoholic actor John O'Malley (John Cullum), in a touring production of Man of La Mancha. He must prevent the obnoxious actor from ending his career with a drunken fall on stage that breaks his leg. This situation is greatly complicated when Sam decides that he does not want to leap after meeting actress Nicole (Michele Pawk), the former piano teacher whom he had a boyhood crush on – and who is in love with Sam's host.

Sam is Timothy Mintz (Donald P. Bellisario), a parapsychologist working with Troian Claridge (Deborah Pratt), a young widow who insists that her late husband is haunting her. The husband drowned in a lake on the property, though he body was never recovered – the same fate as his ancestor, Priscilla Claridge, in 1840. Sam's mission is to keep Troian from drowning in the same lake. Sam gets little help from the other residents in Troian's mansion, her brother Jimmy (Robert Torti) and housekeeper Miss Stoltz (Carolyn Seymour). A device that Sam's host invented to record paranormal activity detects Sam's leap in, and allows those near it to hear Al, though it does not explain how Miss Stoltz looks straight at Al when he first appears. Sam is able to find electronic devices that reveal that Jimmy is using to "haunt" his sister, hoping to have her committed and giving him access to her fortune. The Sylmar earthquake dislodges bodies from the lake bottom, including the ancestor, revealed to be Miss Stoltz, whose ghost had been serving as the housekeeper.

Sam leaps into all-American college jock Knut "Wild Thing" Wileton (Jeff Benson), who must prevent anti-war protests from turning violent and resulting in the destruction of the science block and killing a student unexpectedly inside, thus ruining the life of Elisabeth (Stacy Edwards), a young woman opposed to the war.

Sam is Linda Bruckner (Molly Meeker), a divorced mother juggling raising three children and her job as a realtor. Sam must save her 15-year-old son, Kevin (Michael Stoyanov), who will disappear in the next 24 hours, only his bloody clothing found months later. Matters are initially complicated when Al and Sam are visible to the pre-school child, Teresa (Troian Bellisario), but she and Al become friends. Kevin is sweet on fellow student Jackie Arnett (Allison Barron), who is willingly treated as a strumpet by other male students. When three of the others convince Jackie to embarrass Kevin with a feigned sexual encounter, he runs off into the night, only to be kidnapped by two perverts in a van. Al guides Sam to the van, where he discovers that he is trained in numerous martial arts, dispatching the killers. At school the next day, Jackie apologizes to Kevin and asks him out.

Sam leaps into Eddie Vega (Corey Smith), an El Camino High School football player being raised by a single father, Manuel (Pepe Serna). Sam must prevent his host's best friend, Chuey Martinez (Richard Coca), from throwing the big game and ruining both their chances at college scholarships. Chuey is being pressured by local gambler Ruben de Guerra (Fausto Bara), who will otherwise force Chuey's illegal immigrant single mother, Celia (Ruth Britt), to have sex with him or face deportation. Sam manages to talk Chuey into helping him win the game, but does not leap out until he helps Manuel and Celia admit that they love each other and should get married.

Sam leaps into Buster (Jay Boryea), a bouncer in the middle of an infant kidnapping scheme with Bunny (Julie Brown), a ditsy, compulsive liar as his partner. Sam and Al cannot agree on whether Sam is there to help the pair succeed to take the baby to Clayton, New Mexico or return her to her rightful guardian.
