Scott Kinney is an American geologist monitoring a local volcano when the Supergator, a Deinosuchus recreated from fossilized, preserved DNA escapes from a secret bio-engineering research center/laboratory. Along the way, it eats many people, including 2 lovers, 3 drunken teens, 3 models, 2 tourists and a fisherman. It also eats Alexandra Steven, and Ryan Houston Kinney joins forces with another scientist and a Texan alligator hunter . They pursue the monster as it heads down river intent on destroying a luxurious resort packed with hundreds of tourists. Guns and other weapons have no effect on it at all, so they plan a trap for it using a fake volcano. They lure him on to it, with the Texan alligator hunter as live bait. Supergator gets him and is blown up with poisonous gas, strong flames and a shotgun.
