In a small Louisiana town on the Atchafalaya Basin, a local drunk is found mangled to bits, his death blamed on the Broussard family's pack of "escaped" alligators. But Rachel Broussard claims to have seen the fin of a shark in the swamps. She begins the hunt to find the creature to clear her name and prevent the deaths of hundreds set to fill the river for Gator Fest. But can she stop the "Swamp Shark" in time to prevent the unwitting folks at the upcoming Gator Fest from being torn to shreds!?
