Leonardo Da Costa is a lighthouse keeper stationed in the small hamlet of Cabo Polonio on Uruguay’s southeastern coast. The area has no road access and is largely cut off from the rest of the world, but the lighthouse there has helped guide ships on this treacherous bit of coast since 1881. Through fleeting glimpses of Da Costa’s home, work and daily routines, but without a single line of dialogue or clear shots of his face, filmmakers Diego Vivanco and Ian Clark give a sense of this disappearing way of life as automation closes in on the last lighthouses around the world.
