It's been years since Andy Barclay's encounter with the sadistic possessed Good Guy doll Chucky. Since then, Andy is now grown and has a family of his own. For their son's birthday, they decide to go up to a local cabin with their friends, the Deckard family. Much to Andy's chagrin, one present his son asks for is a Good Guy doll. His wife convinces him to buy one after convincing him Chucky is gone for good. During the party, their son Billy and his friend David play with plastic digging tools, eventually finding the Heart of Damballa and a pot of gold that belongs to a sadistic Leprechaun, who later uses the amulet to awaken Chucky to help him after learning the area is covered in four-leaf clovers. The two horror villains form an alliance, which later ends after Chucky discovers the gold and plans to take it for himself after possessing Andy's body. The two villains clash with each other, leaving the two families in the middle of it all.
