A group of high-school friends, celebrating their reunion, take a trip to the remote Black Lake.

Drifting in a leaky boat with no oars, they are attacked by a hulking, bloodthirsty, underwater predator. Fighting to stay alive as the creature slowly picks them off one-by-one, they are forced to test their friendships as they make the ultimate sacrifice during their terror-stricken fight for survival.
