A youg woman is discovered hanged in a room in a decrepit hotel, and Gothenburg’s Chief Inspector Erik Winter must try to figure out what happened. As Winter looks around, he realizes that he was in the same hotel room many years earlier, when it was the last known location of a woman who subsequently disappeared and was never found.
The two women seem to have nothing in common except for this hotel room, but Winter suspects that there may be other connections.
The young woman’s parents are bereft and unable to explain the puzzling contents of a note she left behind. Winter, however, senses that they are holding back some secret that might help him to find her murderer. As he pursues his hunch and digs into the old police report on the woman who disappeared—one of his first cases as a young detective—Winter becomes increasingly convinced that the two cases are somehow related.
