In the year 2038, there are only a handful of honest cops in Detroit, a city run by brutal mafia families. Detective Dane Shannon is waging a war of revenge against the men that destroyed his life. Determined to track down the killers, he accepts every assignment, no matter how dangerous. Punch Back is an underground club catering to the vicious world of savage boxing where the losers are forced to engage in kinky acts of sex. The prize for the victorious fighters is a chance at winning the championship and securing a place in the upper echelon. It’s also a perfect method for the Luciano family to take back their lost turf. Suddenly the losers are winding up dead, the owner suspected and Dane goes undercover.
Steele Lungren is the co-owner, a massive Russian with a dubious past. Angry at being in the middle of a waging war, he has nowhere to turn when he’s pushed against the wall while his partner and current lover questions every decision. As Dane begins racking up wins, his attraction for Steele places the case in jeopardy. Forced to work together or one or both could end up slaughtered, they enter into a relationship that neither understand and the killer unleashes a weakness. Just as the killer is about to strike, certain truths are revealed. In the end, one of them will lose their battle with humanity and perhaps their life.
