It is about two co-workers in a lighthouse while they are in their four weeks shift. The two workers are an experience one (Thomas) and a young man (Ephraim). Soon, Ephraim starts to suffer from the work, the isolation of the place, Thomas's treatment and hallucinations. It is recorded in an old form (1.19:1, black and white image format) and the speech of both characters is rude, which sometimes makes the dialogues difficult to understand. In my opinion is a weird film.
