Lucy's getting very annoyed that her husband Bill and his friend Evan have been working seemingly nonstop on their potentially prize-winning pumpkin catapult. But when the day of the big contest arrives, Evan is nowhere to be found, until a catapulted pumpkin busts open the trunk of the Dodge. Amid the pumpkin gore is a very deceased Evan. Bill is on the hook for the Halloween homicide, so Lucy knows she's got some serious sleuthing to do. With each new lead pointing her in a different direction, Lucy sees that time is quickly running out. If she wants to spook the real killer, she'll have to step into an old ghost story.
