Stam, a not so smart cop, must figure out if a random assault on a young woman, Vivian, is connected to a killer stalking Pittsburgh and removing victims' brains. And why is Viv losing her smarts while becoming aggressive and violent?

A group of teenagers escape to a cabin in the woods for a spooky, drama, and fun- filled getaway, and, coincidentally, so does a deranged psycho known as The Reaper, a young man who committed terrible acts years ago in these same woods. Unfortunately for the teenagers, it's The Reaper's very special anniversary, and he has only one way to celebrate.
