In a small town, the silence is shattered by a rash of disappearances at the swamp near the old deserted factories. Bodies are being discovered with no blood left in their bodies. It's up to a park ranger and the town sheriff to discover what ungodly creature is responsible for these deaths. It's only a matter of time before they discover that what they seek are Leeches that have grown to unbelievable size. We bleed- they feed!
