This film has the entire tenant squeal on a drug dealing gang to the police, only for them to get out, and one by one, they go to each tenant in the floor, killing and torturing them in an ugly fashion, making their way up to the top floor tenants, as the tenants either run to the top, or just stay in their rooms, waiting for their inevitable deaths. You see some repulsive violence, as well as pure sadism that would make Abel Ferrara proud as it out-Abels Abel Ferrara films in capturing the down right seediness and the hopeless and the no way out living of being holed up in these poor buildings. With each new death, you just realize there is no way out for these poor souls, and that they are facing inescapable death. Very grim, especially being directed by a woman! The ending is very corny, which kind of shifts the mood of the most of the film, almost ends like a Monty Python skit, but ignoring the last 5 minutes, this is a ride into despair and hopelessness that you will soon not forget. Just down right ugly! You'll will NEVER want to rent a New York poor apartment house after seeing this film!
