Alligator

“It lives 50 feet beneath the city. It's 36 feet long. It weighs 2,000 pounds...And it's about to break out!”

David (Robert Forster), a rumpled detective with a bad reputation on the force, wants one case that clears his name. He gets a sewer-dwelling alligator grown huge on discarded lab animals, and he teams up with Marisa (Robin Riker), a reptile expert, to chase it. Lewis Teague shoots the city in grainy, low-lit streets and lets the thing move through town in the dark. David keeps going after it, even though nobody on the force believes him.
