After an innocent man is released from prison for a crime he did not commit, he seeks out the people he believes responsible for his destiny's unfortunate path...under the impression that he is dieing of a disease due to a disturbing experience in jail, Murphy Berserk decides to no longer be the "forced" one in his life, but the "enforcer." He takes the advice of his long time war vet friend and decides to "cut all his ties, and end every game you started on this god-forsaked earth.
