A man living with his parents in a low middle-class apartment in Rio de Janeiro coldly stabs them with a razor and then goes to the movies. Marcia, a rich and dissatisfied young woman, takes advantage of a trip from her husband to go to her home in Petrópolis, where she receives a visit from an old friend, Regina.
