After the Museum of Yankee Horrors wins first place?and $10,000?in the town's official Haunted House contest, one of the contest judges is murdered, and it is up to Liz Montgomery to unmask a sore loser.

With Independence Day fast approaching, Liv Montgomery is swamped coordinating one of the town's biggest festivals. In addition to the traditional July fourth events, the town stages a spooky Revolutionary War reenactment that can't be missed. Every year, the ghost of local war hero Henry Gallantine--played by his eccentric descendant of the same name--appears at the top of the family mansion, kicking off the night's revelries.
