Chris and Cathy survived their tortuous grandmother to make a life together and have two children of their own. Everything seems fine until an old woman invites their son Bart in for milk and cookies, and says to him, "Why don't you call me Grandma." Soon after, the sweet, imaginative child begins to undergo drastic personality changes.
