In the gritty streets of Detroit, The Jazz Fight follows Benny "The Hammer" Leonard, a once-promising boxer whose career has been derailed by his own demons—alcoholism, anger, and a destructive past. After a brutal loss in the ring and a nearly fatal bar fight, Benny is pushed to the edge of self-destruction. But when he receives an offer for one last fight, his shot at redemption hangs in the balance.
