Ulises, Jordi Mollà arrives in Dénia, a sunlit coastal town near Valencia, to teach literature. He finds a modest room at a local hostel and is immediately drawn to Martina, the landlord's daughter, whom he notices while she hangs laundry on the line. Martina, Leonor Watling, is warm, enigmatic, and carries a dreamer’s spark that catches his attention from the very first moment.
A local businessman named Sierra, Eduard Fernández, is also captivated by her, but Martina resists his advances. She invites Ulises to see the Son de Mar, a yacht tied up nearby that had starred in a film years earlier when she was a girl of 13. Her dream is clear: to own that boat someday, to ride its memories into a future of wealth and independence. The two form a bond built on shared stories and quiet evenings, and Ulises often recites passages from the Aeneid for her, drawing her deeper into the romance of Dido and Aeneas.
Enchanted by his romantic quotations, amidst the Valencia scenery, she falls in love with Ulises and becomes pregnant. They marry and welcome a son, Abel, into their growing world. Life seems to align with Martina’s long-held desires, and the couple revels in their growing family. Yet the calm surface hides the tremors of desire and choice that will soon pull them apart.
One evening, Sierra invites the couple to a party, and Ulises experiences a magnetic pull toward a mysterious woman dressed in red. The next day, Ulises goes out on his boat to catch a tuna for Martina. A sudden storm rocks the sea, and his boat is found wrecked; Ulises disappears. He is presumed dead, and a funeral is held for him.
Left alone with a very young child, Martina marries Sierra and embraces the wealthy lifestyle she had always imagined. Five years pass, and the man who vanished returns with a longing that cannot be quieted. Ulises reaches out to Martina, telling her, in a voice that carries the weight of every mile traveled:
> It has taken all my travels to discover that I cannot live without you.
Martina struggles with the pull of his words, torn between a life she built with Sierra and the lingering passion that still burns for Ulises. The revelation of Martina’s infidelity spurs Sierra to drastic action, as he sabotages the Son de Mar in a bid to keep her for himself. The lovers seize the chance to escape, steering their fragile fate across the open ocean.
In the heart of the sea, catastrophe strikes. The Son de Mar sinks, and in that moment of final surrender, the lovers find a sense of peace that transcends their earthly troubles. The story closes on a somber, almost mythic note: love, tested by time and circumstance, endures in its most sacred form even in death. The sea returns what life cannot, leaving behind a memory as vast as the horizon they once chased together.
