Alex Blake, an ex-prize fighter, works the night shift and keeps to himself. Things change for him because of two women, a hooker trapped under a sadistic pimp, and a Harvard grad student working on her doctorate who moves into his apartment. Alex is a nice guy, but has a lot of rage inside, which gives him a temper that he has more and more trouble controlling. We slowly learn through the course of the film why he lost his will to fight, and how interactions with the two totally opposite women end up causing him to "fight his fight."
