Seed Of Chucky

Six years after the events of Bride of Chucky and Child's Play 3, the movie opens with Glen, the apparent "son" of Chucky and Tiffany; born at the expense of his estranged mother Tiffany dying immediately after he was born (this is shown at the end of "Bride of Chucky") and living a life of embarrassment and abuse as a ventriloquist's dummy who shortly said he found him long ago in the cemetery of where Glen's mother died. Desperate to know his parents (after seeing behind the scenes footage of the Child's Play movie-within-a-movie on TV), Glen escapes and tracks them down to Hollywood.

Upon tracking down his parents, who are now dummies in one of Jennifer Tilly's films, Glen uses a voodoo amulet (the "Heart of Damballa" from the previous film) to bring them back to life. Shortly afterward, when Chucky finds out that Glen is his child, he faints while Tiffany hugs her son. Shortly after this, Tiffany and Chucky have a dispute over whether Glen is a girl or a boy. Chucky decides to label him as a boy regardless. Tiffany disagrees, labels him as a girl, and calls him "Glenda". This may be a throwback to the Ed Wood 'so-bad-it's-good' movie "Glen or Glenda?".

When a puppeteer, Tony Gardner walks into the room, he picks up Tiffany and begins taking her apart, causing her and Chucky to cut his head off with a piano wire. Jennifer Tilly walks in and sees the decapitated body and calls the police. Glen/Glenda is horrified by this, and later on (after Glen/Glenda explains that he/she is their child) he/she asks them why they murder people. Chucky tells him/her that it's a hobby and they do it to relax. He also states that it has been a tradition for generations. After Glen/Glenda counters by saying that violence is bad, Chucky claims that it is violins that are bad, and that "their screechy music's gonna ruin the goddamn country!" Tiffany, on the other hand, calls it an addiction, and tells Chucky that they need to stop, since they have a child and a future to think about. She and Chucky make an agreement to quit killing, although Chucky pretends to agree, crossing his fingers behind his back and promising so Tiffany will shut up. Meanwhile, Jennifer Tilly tries to get a role as the Virgin Mary in Redman's directorial debut, but after Redman says that Tilly isn't right for the part and that he is going to go with Julia Roberts (who Tilly hates), Jennifer invites him over to her house. As this is happening, Chucky and Tiffany make plans to transfer their souls into Redman and Jennifer so they can be married with children. However, Tiffany says that she will not let herself get pregnant again, and decides to make Tilly the surrogate mother. Meanwhile, Jennifer Tilly and Redman start to have sex only for Tiffany to knock them both out. While they are knocked out, Tiffany inseminates Tilly with Chucky's semen. As this happens, Chucky leaves and takes Glen/Glenda with him. After driving Britney Spears' car off the road, they proceed to go to a photographer's dark room. The photographer (John Waters) had taken pictures of Tilly having sex with Redman, and of Chucky masturbating. While Chucky attempts to kill the man, Glen/Glenda tries to warn him, only for the photographer to bump into a shelf causing a jar of acid to fall on his face. Chucky is overjoyed at this, thinking that Glen/Glenda wanted to kill the man. He takes a picture to celebrate.

Jennifer Tilly awakens the next morning without remembering the previous night. She proceeds to have morning sickness and realizes that she is pregnant. After telling Redman, claiming it is his, he states that this is impossible as she answers the phone. After Tiffany hears Redman's reaction, she is unable to control herself and guts him, hiding his body in a closet. The next day, Jennifer Tilly awakens and is horrified to find herself with a fully-pregnant belly.

The voodoo magic that "fuels" the killer dolls has also accelerated the pregnancy. Tilly is then captured by Chucky and her chauffeur, Stan (serving as a replacement body for Chucky due to Redman's death). Tilly's assistant, Joan, concerned about her boss, tries to help her, but she is killed after she is lit on fire and falls to her death. Although it seems that Tiffany eliminated Joan, it is revealed that it was Glen who turned into Glenda (it is revealed two souls share Glen's body, shocking both of his parents and himself after Tiffany snaps him out of it). Chucky puts a cloth in Tilly's mouth to keep her from talking and screaming.

Later, Tilly gives birth to twins, a boy and a girl. It is then that Chucky has an epiphany. After several years of being an infamous killer doll, Chucky finally accepts (and embraces) his circumstances. Disturbed, Tiffany rejects Chucky and resolves to take Glen with her. However, an enraged and emotionally shattered Chucky throws a knife at Jennifer, but Stan jumps in front of it and is killed. Before Stan dies, he tries to tell Jennifer that he loves her. Tiffany takes the knife and throws it at Chucky. Before he can take it and before Glen can decide which baby to possess, the police arrive, forcing the dolls to flee. Jennifer is rushed to the hospital, once she is found by the cops. Jennifer claims she wants to see her babies. While looking at her twins' pictures, Tiffany takes a needle and drugs Jennifer. She tries to possess Jennifer, but Chucky breaks the door with an axe and kills Tiffany after she possesses Jennifer. Glen follows after his mother's orders and decapitates Chucky after Glen chops off Chucky's arms,and legs. with the axe. After suffering a breakdown, Jennifer (Who's really Tiffany in Jennifer's body) comforts her son.

Five years later, in 2009, in a middle of a birthday party, a woman quits her job as a nanny because Jennifer's daughter stares at her with hate. Jennifer gradually lets her quit, only to kill her when she turns away, and Jennifer's eyes switch to Tiffany's, meaning they have now switched places; Tiffany in Jennifer's body, while the real Jennifer is assumed to be dead. Glen now takes the body of the son, and at the twins' birthday party, receives a strange present with no name. When Glen opens the present, he sees it's Chucky's right arm. Glen, frightened, starts twitching and wets his pants (for the third time). When he turns around, Chucky's arm grabs him and he begins screaming while Chucky's laugh is heard, meaning he will return.
