Four years after the events of Curse of Chucky, an adult Andy Barclay still has the head of Chucky, which is conscious and deformed after being repeatedly tortured by Andy in retribution for his crimes. Meanwhile, the wheelchair-bound Nica Pierce has spent the past four years in a mental institution after being framed by Chucky for the murders of her family. After therapy, she now believes she was responsible for the murders and that Chucky was a manifestation of her psychosis. Dr. Foley, Nica's doctor, has her transferred to the medium-security Harrogate Psychiatric Hospital.
In group therapy, Nica meets Malcolm, a man with multiple-identity disorder; Angela, an old woman who believes she is dead; Claire, a woman who burned her house down; and Madeleine, a patient who smothered her infant son to death. Dr. Foley introduces a technique involving a Good Guys doll. Most of the patients are unsettled by the doll except for Madeleine, who treats it as her baby.
Nica is visited by Tiffany Valentine, the legal guardian of her niece Alice. She is devastated when Tiffany informs her Alice has died, apparently from a broken heart. Tiffany leaves Nica a Good Guys doll, which she claims was a gift from Alice. That night, Chucky awakens and discovers Nica has attempted suicide. The next morning, Nica finds that her wrists have been stitched up, with a message stating "not so fast". She discovers Angela has been killed, leaving the message "Chucky did it." After realizing that Valentine was the last name of Charles Lee Ray's girlfriend, Nica understands Chucky is real. Fearing Madeleine is in danger, Nica has Malcolm try to warn her. However, Madeleine throws both the doll and Malcolm into an empty grave. The orderlies rescue Malcolm.
Claire attempts to get rid of Chucky by dumping him down the garbage chute, but he bites her arm. The orderlies sedate Claire, believing that she was harming herself. Chucky then kills Claire by launching a compressed air tank into the skylight, causing glass shards to decapitate her. Andy learns about the murders online and realizes Chucky has somehow managed to transfer his soul into multiple bodies at once. In a private session with Foley, Nica agrees to be hypnotized in order to access any repressed memories about her involvement in the murders. Foley, who has been sexually abusing Nica, is hit from behind by Chucky. Foley believes Nica is the one who assaulted him but is willing to keep quiet in order to blackmail her for sexual favors. Madeleine smothers her Good Guys doll with a pillow, forcing her to confront the repercussions of her real child's death. Orderlies bury the doll in order to placate Madeleine.
Determined to end the carnage and save Nica, Andy commits himself into the institution by assaulting one of the security guards. Carlos, a nurse, delivers a package to Foley: another Good Guys doll. Madeleine is visited by her own doll, which has risen from the grave, and she allows the doll to kill her so she can finally be with her baby. Foley attempts to assault Nica but is knocked out by one of the Chucky dolls. Two dolls are now alive due to Madeline's doll splitting its soul inside of Foley's doll. One of the dolls awakens the short-haired doll Andy had sent with a weapon inside. The three Chuckys reveal that the original Chucky found a voodoo spell on the internet, which allowed him to separate his soul into multiple host bodies and thus creating a "cult". Alice was one host, but she was killed in a physical altercation. All the dolls then kill Carlos in front of Nica.
Tiffany returns and kills a security guard by slashing his throat. Foley's Chucky doll transfers his soul into Nica, giving her body the ability to walk again. She then stomps on Foley's head, using high heels that Foley had given Nica earlier, killing him. She stumbles upon Malcolm, who confessed to killing Nurse Ashley, and is subsequently killed by Madeleine's Chucky. Andy's Chucky, the short-haired one, attacks Andy, but Andy reaches into the doll's chest and pulls out a gun he had planted there. He shoots the doll and stomps its head, killing him. Nica appears and taunts him. He tries to shoot at her, only to discover that he has no ammunition left. The institution is sent into lockdown, resulting in Andy being locked inside his cell.
With Andy's Chucky defeated, Madeleine's Chucky goes into doll mode and Nica, possessed by Foley's Chucky, ends up escaping. She "reunites" with Tiffany before driving off together with the Tiffany doll, which is revealed to be alive as well sharing a portion of Tiffany's own soul.
In a post-credits scene, Andy's former foster sister Kyle enters Andy's house, having been sent by Andy (implied to have escaped from the hospital) to continue torturing the original Chucky's severed head while he went to save Nica.
