The movie follows the infamous killer doll Chucky (voiced by Brad Dourif) and his equally malevolent partner Tiffany (voiced by Jennifer Tilly) as they return to wreak havoc once again. This time, they are accompanied by their child, Glen (also voiced by Billy Boyd), who is a gentle and kind-hearted doll struggling to come to terms with his family’s murderous legacy.
The story begins when a British ventriloquist, Hannah (played by Hannah Spearritt), acquires the Chucky and Tiffany dolls for her ventriloquism act. However, when she inadvertently brings them to life using an ancient amulet, Chucky and Tiffany seize the opportunity to use Hannah’s body as a vessel to conceive a child.
Meanwhile, Glen, who has been living in England with a sideshow ventriloquist, learns of his true parentage and sets out to reunite with his parents in Hollywood. Along the way, he encounters a film crew shooting a movie based on the “Chucky” legend, including the actress Jennifer Tilly (playing herself).
As Chucky and Tiffany scheme to transfer their souls into human bodies and live out their twisted fantasies, Glen struggles with his identity and desires to break free from his family’s violent legacy. Ultimately, Glen must confront his parents and decide whether to embrace his dark nature or reject it in favor of a more peaceful existence.
In the climax of the film, a violent and chaotic showdown ensues as Chucky, Tiffany, and Glen face off against each other and their human adversaries. In the end, Glen manages to reconcile with his parents and reject their murderous ways, while Chucky and Tiffany meet their demise in a fiery explosion.
The film concludes with Glen assuming a new identity and beginning a fresh start, free from the horrors of his past. As he walks away from the burning wreckage of his former life, he reflects on his journey and looks forward to a future filled with hope and redemption.
Overall, “Seed of Chucky” is a darkly comedic and self-aware installment in the “Child’s Play” franchise, blending horror, humor, and satire to create an entertaining and twisted tale of family dysfunction and the consequences of one’s actions.
