Everyone is trying to get Ritchie "Redrum" Abruzzi to make a comeback in the boxing game. What they don't know is that he's still fighting, only now in bareknuckle, high-stakes underground matches where the winner comes out with a handful of cash and the loser gets a trip to the hospital, if he's lucky. He's also still struggling in the shadow of his father Ritchie "Bam-Bam" Abruzzi, a former world-champion whose accomplishments dwarf those of his son. To make matters even worse, Ritchie has started receiving threatening letters from the son of a man he killed in the ring more than a decade ago. Throw in an ex-wife always after him for the child support, and an unexpected offer from a mysterious b-movie director in Hollywood to star in a low-budget film, and things are about to get interesting- and quite bloody- for Ritchie "Redrum" Abruzzi.
