Lying at the bottom of his apartment stairs, a postman is found dead.

At first glance, his death appears to be a tragic accident. However, when Detective Superintendent Konrad Simonsen is called to investigate, he notices that something doesn't add up. Did he fall?

When life-sized images of a vanished girl are discovered plastering the walls of the dead man's attic, the case takes a new and sinister turn. Who is she? Could she be alive?

Soon the homicide team find themselves delving into the past, but as they approach the truth, Simonsen is forced to confront long-hidden skeletons in his own cupboard.
