Six high-school graduates venture to a secluded lake for a weekend celebration, but become stranded in the water when a flesh-eating creature emerges from the depths. Now, trapped in the treacherous waters without an oar, the teens must figure out a way to reach the shore without getting devoured. Meanwhile, distrust and infighting threaten to be their undoing before they even dare to face the terror below.
