Facing the threat of suspension, a detective from the big city teams up with a small-town sheriff to look into a seemingly straightforward missing persons case. However, they soon uncover a disturbing pattern: every year for the past two decades, at least one girl has vanished from this quiet fishing village. When a body is discovered in the lake and suspects begin to emerge from the surrounding hills, the two officers realize they are being manipulated. To complicate matters, the murderer appears to be targeting a group of sorority girls who are not only secluded by the lake but also harbor their own sinister intentions. With limited resources and options, the detective and sheriff must unravel the mystery of the missing girls or risk becoming victims themselves.
