No Redemption With... Don Mitraglia(2012)

An upright priest, disliked the corrupt upper echelons of V.A.T.I.C.A.N.O., is imprisoned, tortured and sentenced to certain death. But by divine intercession he'd be able to save himself: once put back on track, and trained in the martial arts by an eccentric monk, he will take revenge in a crescendo of disproportionate violence.
