An alien starship crashes in a swamp in a U.S. National Park. Some mosquitos begin to feed from the alien's corpses, causing them to grow to the size of a vulture. These mutant insects became very agressive, killing every human being they find. Will the few survivors fight successfully against this nightmare...?

A duo of gun happy redneck hunters stupidly break a sacred circle in a hunting spree, which releases the deadly wendigo. The wendigo kills many of the hunters gruesomely, leaving the chosen woman and a gun toting idiot to destroy the deadly beast.
