Nika Pierce has spent four years in a mental institution, and she is convinced that she is responsible for her family's deaths, not Chucky's doll. When the doctor suggests a new therapy involving a doll with a kind face, people start dying in the institution, and Nika begins to believe that her nightmares are real. Andy Barclay has grown up and is on his way to help, but he is opposed by Tiffany, Chucky's fiancée, who is willing to do anything to protect her beloved.
