When serial killer Charles Lee Ray (Brad Dourif) is mortally wounded in a police shoot-out, he uses a voodoo spell to transfer his soul into Chucky, an innocuous ‘Good Guys' doll. Young Andy (Alex Vincent) receives him as a birthday gift, and Chucky soon embarks on a killing spree. However, Charles doesn't want to be trapped in the body of the doll forever; escape is possible by transferring his personality into the first human he reveals his identity to... and naturally Andy is curious about his new toy.
