Set during Christmas, Blasphemy tells the comedic story of what happens when Martin Garcia (Carlos Leon) reveals to his devoutly religious family that he doesn't believe in God. His mother turns to her fanatically religious sister, Patricia (Karmin Murcello) for help. Unfortunately for Martin, Patricia soon concludes that he's been possessed by the devil. She vows to "save" Martin, even if she has to kill him. A chorus of gods and Prophets, including Abraham, Jesus, Mohammed, Buddha & Lord Krishna, provide a running commentary.
