Three episodes based on the short stories of Brazilian playwright Nelson Rodriguez. In "First Sin," a clumsy n'er-do-well is approached by a beautiful woman to help her betray her husband; "Diabolic" follows the story of a man who falls to pieces when his fiancee's 13-year-old sister puts the moves on him; and in "Son of a Bitch," a betrayed husband catches his wife and best friend meeting for a romantic tryst.
