Swamp Shark (2011)

Open on gorgeous swamplands of the Atchafalaya Basin in the summer Lots of beautiful teens are at the beach the weekend before Gator Fest That night an animal smuggling deal goes wrong and a large sea creature escapes into a swampy backwoods river At the McDaniels Gator Shack restaurant a local Jackson is drunk and gets mangled to bits The town sheriff blames the carnage on the McDaniels escaped pack of gators and tries hauling them off to jail Rachel McDaniel head of the family claims to have seen the fin of a shark Rachel and her family along with the help of a mysterious stranger Charlie take on the Swampshark and the law to clear their names save Rachels kid sister Krystal and prevent the unwitting folks at the upcoming Gator Fest from being torn to shreds by a beast the likes of which no one has ever seen
