After months of hot mail, Tanya flies a first time to Atlantic City and they start to have hot sex. Once she's pregnant, she tells Joe she was abused by her wife-beating father, and is again by her husband Mark, a gangster. He realizes paternity is uncertain, but stands by her, and after threats and insults from Mark flies to Pittsburgh, with his gun; from then on everything goes horribly wrong...
