In a forest in Denmark, a ranger discovers the fresh corpse of an unidentified woman. A large scar on one side of her face should make the identification easy, but nobody has reported her missing. After four days, Louise Rick - the new commander of the Missing Persons Department - is still without answers. But when she releases a photo to the media, an older woman phones to say that she recognizes the woman as Lisemette, a child she once cared for in the state mental institution many years ago.
