Twin sisters with contrasting personalities, Ruth and Raquel, rival in the fictional Pontal D'Areia, on the coast of Rio de Janeiro.

After getting lost on a sea excursion, Jô Penteado and Fábio Coutinho develop mutual feelings during the two months they spend stranded on a deserted island.

After his grandfather's death, André Cajarana goes to Rio de Janeiro to understand the death of his father—whom he had always believed to be a hero—and to try to prove his innocence.

Set in Rio de Janeiro, the main plot follows the romantic adventures of four young people: Sônia, Joyce, Paulo, and Carlos. The youngest, Joyce, was raised by her aunt and uncle, Flávia and Dario Rodrigues, following her mother's death and her father's disappearance. Dario and Flávia are Sônia's parents, and they raised both girls as sisters. The story becomes even more complicated with the arrival of Carlos, a young man of humble origins who falls for Joyce the moment he meets her. Joyce, however, does not reciprocate his advances and spurns his interest. Increasingly in love with Paulo, she even pretends to be blind after an accident—solely to remain close to the doctor—and proves willing to do whatever it takes to keep Sônia out of her way.

Eugênio Fontes is a medical student striving for upward social mobility. His impoverished childhood left him with an inferiority complex that hinders him in both his career and his romantic life; consequently, his struggles and dreams are entirely focused on achieving financial security. Deeply conflicted, he feels unable to love his parents, Alzira and Ângelo, to whom he owes his education. While in medical school, Eugênio meets Olívia Miranda, and the two fall in love. However, he ultimately marries Eunice—a beautiful, wealthy young woman and the daughter of the industrialist Cintra. Through his marriage to Eunice, Eugênio secures a good job and gains influential connections, such as a friendship with Felipe Lobo, a respected architect and associate of his father-in-law. Yet, as time goes by, the young doctor begins to question his marriage.
