Two sisters love to have fun, but they are always scolded by their older sister.

Sisters Susana, Márcia and Xuxu live comfortably in a mansion, serviced by maids and a gardener. Susana, the eldest, is a fake puritan while prostituting herself but falls in love and leaves prostitution. Her place is taken by Márcia. Xuxu, the most naive of the three, also finds a boyfriend.
