Porto Alegre, 1930s. Dr. Eugênio Fontes, a recently graduated doctor, is a man divided on almost all levels of human behavior. His inferiority complex in relation to his poor origins does not allow him to fully love his parents, the simple-minded Ângelo and Alzira. Just as he refuses to accept the pure love of Olivia, also a doctor, a fellow graduate, a woman with an admirable character.
