In a small coastal town in Mexico, a humble fisherman named Kino discovers a spectacular pearl that could change his life and that of his family forever. Hopeful of improving his fortune, Kino plans to sell the pearl and provide his wife Juana and his baby Coyotito with a more dignified life. But his joy is soon overshadowed by the greed and envy that his find inspires.
As Kino navigates a sea of ambition, the pearl becomes a magnet for a series of sinister characters: from an arrogant doctor who sees in the pearl only an opportunity to profit, to the corrupt leaders of the town who are willing to do anything to seize it. As the story unfolds, Kino must confront his own demons: the struggle between his love for his family and the insatiable thirst for wealth that consumes him.
The peaceful life he once knew transforms into a chaos filled with tension and violence. The hope for a better future turns into a nightmare, drawing tragedy into his home. Kino's character evolution presents a profound reflection on human nature, materialism, and the cost of dreams. In a striking conclusion, it is questioned whether the value of the pearl truly equals the happiness and peace lost along the way.
