A group of college friends, including Sara, Nick, Blake, Malik, Maya, Gordon, and Beth, decide to spend a fun-filled weekend at Sara's family lake house on a small island in the Louisiana Gulf. What starts as a carefree vacation quickly turns ominous when Malik is severely injured while wakeboarding, and they discover he was attacked by a shark. With no immediate means to contact outside help due to lack of phone signal, and the nearby marina abandoned, they are left stranded and vulnerable.

As night falls, the group realizes that the lake, unusually infested with aggressive sharks, is not a natural occurrence but a sinister setup. Desperation mounts as they attempt to rescue themselves and their increasingly wounded friends, uncovering dark motives and terrifying revelations along the way. With each attempt to escape met with deadly resistance, the friends must navigate both the treacherous waters and the human threats orchestrating their deadly predicament.
