Visceral: Entre las cuerdas de la locura (2012)

A washed-up boxer waiting for his big break to prove himself worthy of the champion's title finds himself trapped in a hopeless struggle, rejected by his mother and devoid of feelings. But when his manager offers him the chance of a lifetime to fight in a winner-take-all match, the ambitious contender becomes a vessel of pure evil and a relentless instrument of destruction of the human flesh. And with every soul he provides, the unholy bond between him and the infernal guardian gradually tightens, and the bigger the suffering, the greater the reward. Is he hell's next champion?
