After becoming injected with a formula derived from an alien ship, a lab gorilla escapes from his containment and befriends two young boys. The alien formula causes the gorilla to grow to gargantuan size and rampage throughout the city and the boys must find a way to save their simian friend before the army takes him down.

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! Remake of the B-cult classic.
