On a remote storm-battered island, two lighthouse keepers receive an unexpected visit from a mysterious sailor who brings with him a dark secret. As the tempest intensifies, the tension between the lighthouse keepers, who have lived in relative harmony for months, begins to surface. One of them, an elderly man with a rigid and traditional character, clings to the rules and responsibilities of the lighthouse, while the young one, filled with ambitions and dreams of freedom, feels trapped in a monotonous and aimless routine.
As the group faces the brutality of the weather and the solitude of the island, the new visitor begins to influence the young lighthouse keeper, urging him to question his life and his loyalty to the old keeper. Tensions rise when the elderly man distrusts the newcomer, convinced that his intentions are sinister. In an unexpected twist, secrets from the past are revealed, and the elderly man's fears about his place in the world and his legacy confront the youthful rebellion.
With its claustrophobic atmosphere and symbolism-laden narrative, the story questions the nature of duty, the loss of identity, and the struggle for personal freedom. The characters, trapped in their own isolation, are forced to confront both their internal demons and the relentless force of nature in a desperate struggle for survival and self-discovery.
