Sheriff Sam locates Shana at her shop and asks her to help him track the rogue vampires and werewolves. She follows her ex-boyfriend to Florida's swampland, where The Watchers live in luxury. While proclaiming their innocence, the vampire leaders force them to board a plane to Quebec, capturing William along the way.
Once Gregg's men free Linda from the werewolves, she heads to Quebec in search of Shana. Meanwhile, trapped in a building sealed as tight as a tomb, Gregg outsmarts the computer-activated house and escapes.
Vampires and werewolves descend on Chateau Frontenac, and the boardwalk erupts in flames. As the battle for control begins, Shana must follow her heart and choose between William and Sam.
