A New York taxi driver fights against his awful depression by improving the area where he lives. He starts by stopping a thief stealing from a local convenience store, and then tries to encourage a young prostitute called Iris to quit her job by giving her money, in an effort to send her back to her family. Travis soon becomes desperate to "wash all the scum off the streets", and purchases four guns to help with this 'clean-up' process. "You talkin' to me?" Starring Robert De Niro.
