Businessman Bill Masterson is out of his element on a long fishing weekend, but outdoorsman Matt Murphy is there to help. Or so Bill thinks. Matt has his own reasons for bringing Bill out into the 100,000 acres of Virginia`s Great Dismal Swamp. The swamp has plans of its own, and the men struggle against natural dangers, otherworldly scares and a predator -- in the form of reclusive survivalist Croaker Norge. Croaker will do anything to remain undetected and is quick to punish anyone who crosses him. The men`s wives, Cindy Murphy and Tina Masterson sense something`s wrong and start searching for their men. Even as they convince Ranger Rettig to call up an all-out search, Croaker takes things into his own powerful hands. A twisting physical battle turns into a twisted psychological war -- both sides determined to stay alive and free. Anyone can enter -- but not everyone leaves the Great Dismal Swamp alive.
