In Sao Paulo, the ambitious gambler Andre Albino de Souza is the driver and assistant of the wealthy alcoholic entrepreneur Dr. Leme, the owner of the Empresas Leme Reunidas. Andre is also the lover of the estranged wife of Dr. Leme, Raquel. Dr. Leme is a frustrated man since he does not have a child with Raquel and he has two mistresses, his secretaries Jussara and the alcoholic Anita that has become addicted in booze by Dr. Leme and now is abused by him. They spend most of the time in a small ranch in the countryside and Dr. Leme brings the nightclub painter Marcelo to stay with them for a period. The maid Isaura lives in the house with her daughter Dora "Dorinha" that has a crush on Andre. Raquel convinces Andre to kill Dr. Leme, drowning him in the swimming pool simulating an accident since he is drunk most of the time, and travels to Europe to have an alibi. Meanwhile Dorinha seduces Andre and has sex with him. But soon she finds that she got pregnant and schedules with Andre to have an abortion. When Andre is ready to set in motion the scheme to kill Dr. Leme, he learns that Raquel is a manipulative woman and has a lover in London. Andre changes the plan and plot a scheme with Dorinha to use Dr. Leme's drunkenness and needy for a child to convince him that she had one nightstand with him and got pregnant. The plan works well until the day Raquel invites Anita to visit her.
