Kelvin Cheatum is on a mission to save his family's studio from sinking into bankruptcy by producing films that honor his father's legacy of cult classic low-budget movies. Currently, the studio is working on a quirky film called Hamburger Time Traveler Detective and the ninth installment of his father's renowned killer puppet franchise. However, their efforts are being sabotaged by a vigilant blogger known as "Demon Warrior 13," who is organizing powerful boycotts aimed at their productions.
The chaos reaches a peak during a scene involving a puppet explosion, which sparks a full-blown on-set clash. Amidst the turmoil, Tommy Hines, played by [Joseph Porter], arrives with his caseworker [Kelsey Sanders] as part of The End of the Rainbow Last Wish Foundation. Tommy's final wish before succumbing to his illness is to tour the studio and see the famous puppets from the Tiny Terrors series.
In an attempt to lift spirits, Polly Bonderhoof, portrayed by [Michelle Bauer], brings baked goods from her sister in Waco, Texas—including a pastry containing the Gingerdead Man, a puppet with a gruesome past. The Gingerdead Man unexpectedly escapes from the pastry and discovers a spellbook in the prop room. The book details a transmigration spell, which requires carving blood from five victims into a pentagram to transfer his soul into a new human host, but the spell’s ultimate goal is to sacrifice a virgin to complete the process.
As the Gingerdead Man begins to slaughter several crew members in horrific ways, Kelvin and Heather [Kelsey Sanders] work to stop him. The puppet becomes violent, even taking control of a prop robot armed with lasers, disintegrating one crew member. Amidst the chaos, Tommy reveals that he has been undercover as "Demon Warrior 13," faking his illness to infiltrate the studio and carry out a vendetta to destroy it because they ignored his script submissions. Kelvin attempts to negotiate by offering a three-movie deal, but Heather tries to overpower Tommy with an ax. The attempt backfires, and Kelvin is knocked unconscious.
Kelvin awakens on the Tiny Terrors set, where Tommy is in the middle of an incantation from the spellbook. Tragically, the Gingerdead Man fatally stabs Tommy from behind. The puppet, now seeking a new vessel, plans to possess Kelvin instead. However, the dolls from Tiny Terrors, animated by some supernatural force, rise up against the Gingerdead Man. They manage to subdue him, crucify him on a cross, and burn him in a fitting act of retribution.
The chaos concludes with a surprising turn: a movie actor bursts into the scene and guns down all the puppets with an AK-47, ending the immediate threat. The story wraps up showing Kelvin marrying Heather and Tiny Terrors winning Best Horror Hand Puppet Motion Picture. Meanwhile, a homeless man comes across the burnt remains of the Gingerdead Man. Hunger overcomes him, and he bites into the cookie—only to become possessed by the vengeful puppet, hinting that the curse may not be over yet.
