His father commits suicide, leaving him only the old dog Beta and a sense of inner unrest. He sets off south and settles in a small coastal town, where he works as a sports teacher, swims in the sea for hours, and falls in love. This comfortable new life comes to an abrupt end when he begins to uncover a family secret: his grandfather, who bears an uncanny resemblance to him, lived in the area until he disappeared under mysterious circumstances. His search draws the suspicion of the locals, and unusual things begin to happen. On top of that, his illness becomes a hindrance, as he cannot recognize faces. Gradually, he realizes that he is in danger of sharing his grandfather's fate, but by then, the water is already up to his neck... With bright, hypnotic power and a subtle tension, "Flut" tells a story of a search spanning three generations.
