Mary Butterfly, the married exhibitionist, is back, this time in the sun-kissed sands of Ubatuba-SP. With Alexandre's camera capturing every saucy moment, Mary teases the beachgoers mercilessly. Her "casada" status only fuels her desire to be watched, to be wanted. She dances, she touches herself, her fingers slipping into her bikini bottoms, causing her to gasp. The ocean's breeze does little to cool her ardor, as she puts on a show that's equal parts erotic and infuriating for her husband, who's left to film rather than participate.
