Horror movie about the underground.
This women is on the underground but falls asleep. When she wakes up no one is about. She tries getting help from the security person but he won't come down. There's this weird monster thing which tries to get her but she runs away and meets a hobo who lives in the underground. Can't really remember what happens next. But the monster thing gets her and she ends up in this weird Dungeon thing with this other man. I think she may escape in the end but can't really remember!
