Sisters Maria Luísa and Beatriz reacted in different ways to their father's abandonment in their childhoods. Nelson left the family to live with another woman, which indirectly caused the premature death of his wife, their mother, changing the girls' future. Maria Luísa began to take refuge in a world of fantasy and to worship her father. Beatriz, on the other hand, has repressed her feelings and defends herself so that what happened to her mother does not happen to her. The first has her husband Afonso's affection and her father's overprotection. And the second lives with loneliness. In the 1970s, during a masked ball in Venice, Maria Luisa announces that she is pregnant. However, Afonso thinks that his son is the result of a betrayal and takes revenge, having sex with a masked woman. Nine months later, Beatriz has a son, but hides the identity of the father, who may be her sister's husband.
