O Sexo dos Anjos

The Angel of Death sends an emissary, Adriano, to Earth to look for young Isabela. But he falls in love with the girl and tries to take his evil sister, Ruth, in her place. Death does not accept the exchange, but agrees to give the young woman one more opportunity. She can only commit two sins; If you commit the third, you will die. Meanwhile, the genius Ruth mistreats her brother, the deaf-mute Tomás - to whom she attributes the cause of all her problems -, and fights with Diogo, a family friend, until she discovers herself in love with him.
