Captain Bosch (Curry) starts an investigation when his wife doesn't come back from a walk one night. People have been disappearing near this city block for awhile and Bosch meets A.J. Sheppard (Stern) who runs a soup kitchen. He notes that a lot of his regulars who live underground have also come up missing. The city has dumped toxic waste below the streets and the Homeless people are turning into mutant monsters. A photographer (Heard) gets mixed up in the mess while trying to do a story on the homeless people. This low budget horror film has a very good cast for a B movie monster flick. The monsters have a cool look to them but we don't see much of them. There's a lot of rubbery clawed hands pushing doors in and pulling people out of frame, instead of them showing full on monster attacks. There is a decent amount of gore all though it is pretty fake looking. The cover-up by the city is an interesting storyline and Stern as the dirty revolutionary is a lot of fun. Unfortunately the movie never gets scary at all and seeing the mutant monsters more would have helped this. The movie has developed a cult following through the years, but as a monster flick it is pretty tame.
