Leigh is a beautiful girl, eighteen years old, headstrong and rebellious. All she wants from her summer by the lake is a chance to relax and have some fun. And that handsome boy she just met certainly looks like fun. But her summer fling will lead to terror. That night in the old abandoned house will haunt her nightmares for the rest of her life.

Eighteen years later, Leigh's daughter, Deana, doesn't know much about what happened to her mother all those years ago, and she doesn't particularly care. She too is looking for fun. What she finds instead is a shadowy figure out for blood -- and his own twisted kind of fun. Killing Deana's boyfriend is just the beginning. Before he's done, both mother and daughter will be plunged into a whirlpool of fear and madness, from which death is the only escape.
