Nick identifies Joe in a police line-up, but is outraged when the district attorney tells him that the defense will cut a deal for a light sentence, since there is not enough evidence to take the case to trial. At a pre-trial hearing, Nick recants his identification so Joe will go free. After following the gang to their hideout, Nick waits until Joe is alone and stabs him to death. The gang leader, Billy, wants revenge. One of the gang members says his sister saw a man in a suit on the night when Joe was killed. Confirming it was Nick from a newspaper picture, they ambush him on the street. He is chased to the top of a multi-story parking garage, where he is trapped in a car and sent over the edge of the lot.
