Swamps are popular settings for monster features, and in this low-budget, bland version of the genre, a swamp in Louisiana, the Copasaw, becomes home to a new breed of creature -- "nutria-man." Part nutria (an otter-like water-loving animal) and part hairy, murderous, male homosapiens, the mutant is created when some scientists' experiments to create an oversize nutria run "amuck." As nutriaman is out diminishing the local population, some very determined hunters are out to track him down and kill him.
