very depressive movie 
A chick tells her to take the underground, it's safer, she walks into a situation where a pimp is fucking up some woman (at least I think it's a pimp), so dude anally rapes Monica's character for seeing it, then kicks her in the face...the really sick shit, is that someone in the background sees the rape, then walks away
Then there is her man, who I guess is being fisted, I don't know what the fvck was going on...
