'Slayerz', it's America of the not-too-distant future's favourite bloodsport. Fifteen pairs of criminals taken from either death row or a life sentence enter the arena and only one team leaves. Each team of two are linked together by a device called a 'kill switch'. If one contestant dies they'll take the other with them, forcing the pairs of ultra-violent odd couples to work together or perish. When ex-police detective James Hageman is recruited by the Slayerz's producers he sees the deadly game as a potential second chance. But paired up with one of the worst serial killers in living memory, James begins to question what the true cost will be if they manage to slaughter their way to the finish line and go free. Up against hulking Nazis, crazed cannibals, Yakuza assassins and assorted hitmen, lunatics and killers nothing is for certain or off limits. The only rule is the team that slays together, stays together.
