Gwen (Judith Hoag) is a witch, but she's determined to lead a normal life. That means keeping her kids from enjoying Halloween and falling into the throes of this bewitched holiday. Her own mother Aggie (Debbie Reynolds) is also a witch, and very much wants her grandkids, especially 12-year-old Marnie (Kimberly J. Brown), to start accepting their witchy future. Gwen's not having it, but when Marnie and her siblings follow their grandma home to Halloweentown after Halloween, they find out the root of why Gwen is so against the holiday. And when she turns 13, Marnie finds out she's also a witch, and her grandma needs her help to fight the darkness in Halloweentown.
