Checkered Ninja

In Thailand, Danish businessman Phillip Eberfrø arrives to check on his new factory. As a boy named Quang accidentally uses his scarf to create a checkered ninja doll, Eberfrø brutally beats him to death. At that moment, lightning strikes, causing the doll to be possessed by a spirit of a deceased ninja. As the Checkered Ninja ends up on a Danish cargo ship, he is picked up by Stewart Stardust, who gives the doll to his nephew Aske Stenstrøm as a birthday present. At school, the Ninja comes alive and defends Aske's friend, Odysseus, from a bully named Glenn using Aske’s voice. After school, Aske learns that the doll is alive after he insults Glenn. Glenn chases Aske throughout Albertslund and the doll quickly gets rid of him and the two quickly become friends. The Checkered Ninja promises to help Aske, in exchange for him unknowingly helping him get revenge against Eberfrø using his lost credit card as a lie to return it to him. Aske realises that Eberfrø shares the same last name as his crush Jessica. He then learns from his mother that Jessica’s dad is also called Phillip so the Ninja makes sure that Aske is invited to Jessica’s upcoming party on Saturday.

After Aske’s stepbrother Sune, attempts to tell everyone about his crush on Jessica, the Ninja, using Aske’s voice and the school intercom, confesses Aske’s love for her to the whole school. Aske and the Ninja challenge Glenn to a fight on the same day as Jessica’s party. Choosing the playground for the fight, Aske and the Ninja build traps to ensure Aske’s win. On the night before the fight, Aske asks if the doll if he is a real ninja which he responds by telling him about ninja clans that lived in Iga Province and how the samurais were sent to massacre them. A ninja named Taiko Nakamura was given the mission of protecting the clan’s children whilst fleeing the province. But he was betrayed by one of the clan members and led Nobunaga soldiers to Nakamura’s hut. Nakamura killed most of the soldiers but they burnt down the hut, killing the clan’s children. Enraged, he vowed for vengeance in exchange for his soul and committed suicide with his katana (seppuku). His soul left his body and killed the traitor and went on to become an avenging spirit that dedicates himself to protect children.

On the day of the fight, Aske wins, gaining him popularity and causing Jessica to invite him to her party. At the party, Aske and the Ninja confront her father who is not the one the Ninja is looking for as he spells his last name ‘Eberfrö’. Eberfrö gives Aske and the Ninja Eberfrø’s address. The Ninja wants Aske to leave the party to go to Eberfrø’s house but he refuses, causing the Ninja to embarrass him in front of everyone, ruining his newfound popularity. Aske is forced to join after the Ninja insults Jessica using Aske’s voice in which she kisses Odysseus instead, upsetting Aske. The two arrive at Eberfrø's house where the Ninja attempts to kill him. Eberfrø escapes, as does Aske and the Ninja. Aske realises that the Ninja is actually Nakamura. When Aske refuses to help him, Nakamura attempts to murder Sune after what Aske said earlier (“I just wish you were dead”). This makes Aske seem insane, causing him to be imprisoned in an asylum. While in the asylum, Aske and Nakamura strike a deal to bring down Eberfrø without killing him. Visiting Stewart, he gives them a number of a drug dealer who gives them a kilogram of cocaine. Aske inserts the cocaine into Nakamura’s body, intending to frame Eberfrø for possession of illegal drugs, and follows Eberfrø to the airport where Aske and Nakamura emotionally bid farewell. As Eberfrø arrives in Thailand, Nakamura jumps onto him. Police subsequently find Eberfrø carrying the cocaine-stuffed doll. Nakamura’s spirit leaves the ninja doll and Eberfrø is promptly arrested.

Back in Denmark, Aske finds out that before departing, Nakamura sent Jessica a voicemail, using his voice, apologising to her, causing the two to become a couple. That night, Aske sees on the news about street criminals and, inspired by Nakamura, becomes a vigilante, dedicated to protecting Albertslund.
