El Vengador

Deputy Sheriff Michael Kirtchner gets an "unknown disturbance" dispatch call to a remote house trailer in the swamp. There, he discovers an old woman and a dog, terrorized by a mysterious beast, which he takes to be a bear. But when he contacts Game Warden Jeff Stuart to come trap the animal, Stuart tells him to get out if he values his life - this is no ordinary animal. Is Kirtchner up against a Swamp Ape - a Florida version of Bigfoot - or something more...sinister?

Based on a true story.
