Dana and her friends want to spend some "girl time" together after graduation, so they head off to a secluded lake. The same lake where Dana's mother was ruthlessly stalked and almost killed decades prior. But surely, the crazed killer, whose body has never been found, isn't still somehow roaming around that same remote lake looking for hapless victims, is he?....Who are we kidding? Of course he is. That's why they made the movie.
