A woman, swimming in a pond, gets attacked by something we think at first is an alligator. She drags herself out--missing her legs up to her ass. Then, we go to the usual group of college-aged kids who are on a trip. They drop by a roadside store and there's a display about "Lockjaw", which is the South's version of Bigfoot. It's an alligator man.
One of the guys tell the story about the locals becoming sterile because of inbreeding--but the young girl is killed by an alligator. Grimly tracks down the creature, a huge albino alligator and kills it with his bare hands. But his mind has snapped--and he begins eating the leftover human remains. Legend has it that he starts transforming into a monster. In the present, the locals, led by Sid Haig worship the creature and feed it tourists. Creature is a touch Wrong Turn crossed with The Alligator People. And the rubber suited creature is cool looking.
