 Jonnie and Jay Linski are siblings with a heavy cross to bear - the brutal murder of their beloved little brother, Danny. Left reeling in the aftermath of this vicious crime, the Linskis seek solace on society s fringes; older brother Jay indulges in violent criminal behavior, while Jonnie exorcises his demons as a bare-knuckle fighter. Jonnie brutally pounds his way to the top of the illegal fight game, an opulent lifestyle and the love of a good woman going some way to anesthetize the pain he feels over the loss of his brother - that is, until, he overhears a conversation implicating Jay and a rival, Neville Jessoppe, in Danny s murder. Consumed by grief, Jonnie Linski embarks on a disturbing plan to avenge the death of his brother. In the nefarious twilight world they inhabit, however, nothing is as it seems, and Jonnie finds his world rapidly spiraling out of control, culminating in an explosive confrontation between the brothers.
