Howling winds whip through the trees on a stormy night back in the 1940's. An angered man enters the old Victorian house on the banks of Fever Lake. Inside a fearful mother hides her young son in the attic and he soon becomes the only witness to his mother's tragic murder. Years later a group of friends are planning a weekend getaway and are offered the use of the deserted old house on Fever Lake. It started out as a fun filled weekend. But as evil supernatural forces collide with innocent victims, the group find themselves in for a terror-filled stay. Nobody knows exactly what evil went on at Fever Lake, but what they do know is that something evil happened before and it's happening again. They must destroy the evil... before it destroys them.
