At a swamp lake boat rental, two visitors and a young girl are choosing a boat when the man raises an empty gun, claiming it's for hogs. Sara, a woman with them, is visibly frightened, while the girl's mother defends his actions. Tensions escalate as Sara's fears about a threat in the water are mocked by the family, and they ultimately choose the cheaper, vulnerable rowboat against her silent protest. As they board, news reports of multiple disappearances hint at danger, leaving Sara isolated and the group unknowingly heading out into the treacherous waters.
