A group of friends spend a weekend at a lakeside house only to find that danger lurks beneath the waters.

Yet their biggest fear is realised when they discover that the lake's shark inhabitants are not their only enemy. When attempts to skip town fail one by one, these college kids or the ones who are left will have to battle their enemies head-on in order to survive.
