Eric trudges through a stormy night, soaked and exhausted, walking along the edge of a remote road. A truck approaches, slows, and picks him up. The driver, forest ranger Dan Mackenzie, seems like a welcome rescue—until he suddenly snaps a pair of handcuffs onto Eric’s wrist.

Dan brings Eric to the Simms Lodge, where six other stranded travelers have taken refuge from the storm. Mudslides have isolated the area, blocking every road in and out. No one can leave, and the tension inside the lodge rises as tempers clash.

What begins as an uncomfortable night quickly becomes a deadly one. One by one, the guests start turning up murdered, each death heightening fear and suspicion among the survivors. Cut off from the outside world, Eric finds himself trapped in a living murder mystery—part Sherlock Holmes, part nightmare.

Knowing that his own monstrous change is drawing near, Eric urges the remaining guests to search for clues and expose the killer before either the murderer strikes again… or the wolf inside him does.
