In a desolate, sun-drenched Spanish landscape, an inseparable trio since childhood—La Novia (Inma Cuesta), El Novio (Asier Etxeandía), and Leonardo (Álex García)—find their lives inextricably bound by passion, family rivalries, and destiny. Though La Novia is set to marry El Novio in a grand wedding meant to heal long-standing family grudges, an intense, uncontrollable attraction persists between her and Leonardo, who is already married to another woman. On the night of the wedding reception, unable to suppress their lifelong obsession, La Novia and Leonardo flee together into the wilderness on horseback. Their betrayal prompts an immediate, vengeful pursuit by El Novio, leading to a tragic and violent confrontation in the forest that fulfills the dark, blood-bound destiny shadowing both families.
