"Merry Wrath has a problem. Her Girl Scout Troop co-leader has signed them up to participate in a Civil War reenactment based on the little-known Battle of Idiot Creek. In full 19th century costume, Merry is just hoping she can keep her troop out of trouble. Unfortunately, things start to fall apart immediately—from the cannon the kids buy with her credit card, to one girl sneaking off at night to beat the other reenactors at poker, to avoiding a rumble between her troop and the haughty Magnolia Girls.
But things take a sharp turn for the worse when a real human leg appears in the pretend amputation tent...only to disappear while Merry's guarding it."
