Harvey Keitel is great in this film. He plays a crooked cop who abuses hardcore drugs and is in debt to gangsters via his gambling addiction. He has to investigate - of all the horrors in the world - the gang rape of a nun - and along the way experience an opportunity at redemption. The scene at the end where Keitel lashes out yet at the same time begs forgiveness from The Church is unbelievable. Great performance. Great movie.
