Elvis Valderez is a 21-year-old dreamer who has just been honorably discharged from the U.S. Navy. He travels back to his hometown of Corpus Christi, Tex., to seek out his father -- a man he has only heard about from his late Mexican mother. Elvis quickly discovers that his father, David Sandow, is now the pastor of a thriving Baptist church and has a family of his own -- a beautiful wife, Twyla, and two picture-perfect children, Malerie and Paul. Upon learning that David wants nothing to do with him, Elvis resolves to leave David and his happy family alone. But, he finds himself strangely attracted to his 16-year-old half sister Malerie. He befriends her, and their relationship soon develops into something romantic. Thus, he sets the stage for the unleashing of violence and a tragedy of biblical proportions.
