Sharks attack a fish rodeo on the Mississippi River, and it is up to a group of locals to stop them.

Before meeting George Good (Brad Dourif), Sonny Jordan (Mekhi Pfeiffer) was just a lost drifter with a troubled past floating from town to town, looking for work.

Sonny quickly settles in and makes himself useful around the place but then Sonny meets Larissa, (Elika Portnoy) George's alluring wife. She has a mysterious past and the two are irresistibly drawn to each other. The two begin a passionate affair leading them to construct a twisted plot to take George's life in cold blood in order to be together.
