Victor Mancini, a sex-addicted med-school dropout, keeps his increasingly deranged mother, Ida, in an expensive private mental hospital by working days as a historical re-enactor. At night he runs a scam where he deliberately chokes in upscale restaurants to form parasitic relationships with the wealthy patrons who "save" him. When, in a rare lucid moment, Ida reveals that she has withheld the shocking truth of his father's identity, Victor must enlist the aid of his best friend, Denny, a recovering chronic masturbator, and his mother's beautiful attending physician, Dr. Paige Marshall, to solve this mystery before the truth of his possibly divine parentage is lost forever. Based on the novel by Chuck Palahniuk.
