A couple of friends are chased by a killer clown in the woods during a week-end.

At first it was just a joke, a myth around the campfire for five friends staying at a remote cabin in the Texas woods. But when they begin to disappear one-by-one, replaced by bloodied body parts and voodoo effigies scattered among the trees, the remaining few scramble for their lives. But he's out there. And he's sick. And all he wants is blood.
