Beneath the streets of New York city, there are hundreds of miles of subterranean tunnels unfit for anything human, unauthorized for anything experimental and unlikely to come to the surface... until now. Something horrible is loose in the sewers of Manhattan, and the city's homeless population has begun to mutate into 'Cannibalistic Humanoid Underground Dwellers.' They are C.H.U.D. - hideous, hungry and headed for the streets! John Heard, Daniel Stern and Kim Greist star in this wildly original horror shocker, filmed on (and below) the streets of New York City where hundreds of tourists every year are still devoured by actual C.H.U.D.!
