Uma Mulher para Dois (1978)

Solange is seriously depressed, and her kindhearted husband, Raoul, makes it his mission to cure her doldrums. After many failed attempts to cheer her up, Raoul hits upon a possible solution: find his wife a lover. Unfortunately, his choice, Stéphane, proves to be just as ineffectual in restoring her flagging spirits. In the end, the gorgeous Solange finds her own, highly problematic tonic to her troubles in the form of a 13-year-old boy.
