Leonardo Da Costa is a lighthouse keeper stationed in Cabo Polonio, a remote cape in a stretch of Uruguayan coastline rich in shipwrecks and sunken treasures. Cabo Polonio's light has been guiding ships since 1881, and Da Costa is the latest in a long line of watchmen who have operated the tower with care and attention.

He leads an unassuming life, the tranquility of the almost intact landscape keeping him company. Serenity and silence merge with the daily tasks and chores he carries out. Da Costa represents a rare profession that still survives in a few countries.
