Meet Mark 'the smashing machine' Kerr, the undisputed, unstoppable champion of the world's most savage sport. No holds barred 'ultimate fighting' gained massive popularity in the US, even outrating boxing and prowrestling, until it was banned in the mid-1990s. With an inhuman capacity for inflicting and withstanding pain, Kerr is a modern day gladiator capable of almost any savagery in order to survive and win. The Smashing Machine is a visceral portrait of a man willing to sacrifice his relationships, his health to win.
