In Galicia in 1900, two girls are born on the same winter night in the Valdés manor: Catalina, daughter of the Valdés family, and Clara, daughter of the maid Renata. A secret baby swap driven by revenge will shape their destinies forever — Catalina raised in privilege and Clara fighting for a better life without a mother's love.

Upon her return to Punta do Bico, Doña Inés clashes with the Barba Peláez family over control of the sawmill and the workers' labor conditions. She also confronts Catalina, who is becoming increasingly rebellious and confrontational. Renata too suffers from the young woman's slights, keeping silent about the secret that torments her. Meanwhile, Clara regains hope and the belief that she can fulfill her dreams thanks to Celso. Her romance, however, seems doomed almost as soon as it begins.
