Estrella Contreras, a single mother struggling to raise her daughter Azul, finds herself having to return to her hometown after the fateful death of her father Ulises, where she meets Fabián Bravo, a widowed father and fisherman by profession who is fighting to regain custody of his teenage daughter Yazmin. Love blossoms between them, but it will be complicated by the intrigues of Érika Méndez, Fabián's ex-partner, and the ambition of Sergio Falcón, a powerful businessman and Azul's father, who will relentlessly seek to prevent this relationship, even if it means ending the customs and traditions of an entire fishing village, which will lead Fabián and Estrella to face a hurricane of calamities, always putting the well-being of their families first.
Fabián begs Gertrudis to forget the past and let him be close to his daughter, otherwise he is willing to report her, since Yazmín almost died under his care. Gabriel sees a woman floating in the sea and rushes to help her. Estrella informs the family that their bank loan was denied, and now they must dedicate more time to their business on the beach. Iker visits ‘Sirena’ in the hospital to give her the drawing he made of her, but finds out that she will be discharged and asks her father to take care of her. Estrella is willing to become the first female fisherman to support her family and thus pay Fabián every last peso.
