Hart of Dixie celebrates Halloween a week later on Monday.

During "The Undead and The Unsaid," Zoe hits a man with her car, cannot locate his body... and is then convinced she's hit a ghost. But that isn't the scariest thing that happens to this good doctor: her mother comes to town.

Elsewhere, Lavon causes problems for George and Lemon after they believe they've found their dream home.

Watch the promo above and then vote on a separate issue: When it comes to Zoe's dating life, are you Team Wade or Team George?
