Blasphemy the Movie plot
After a heated argument, Martin tells his parents that he is an atheist and that he plans to inform the entire family during the approaching Christmas party. His mother turns to her avid religious sister, Patricia, for help. Unfortunately, for Martin, Patricia concludes that he is possessed by 'the prince of darkness'. She promises to save Martin even if she has to kill him. When Martin shows up at the Christmas party, the family has hysterical fits, except for Patricia, because she has been preparing all her life for this evening, a fight with the devil.
