In Brett Kelly's remake of Roger Corman's 1959 B-movie classic, the horror mounts as the body count rises when residents of a small town turn up with the life literally sucked out of them. The culprit: giant swamp-dwelling leeches. As coeds frolic by the marsh, a ranger and the sheriff begin a frantic hunt for the elusive creatures. Meanwhile, a local scientist offers a radical solution: Blow up the marsh! Mike Conway and Kevin Preece star.
