The body of a young girl washes up dead on the beach at the Elbe riverbank. Her feet are bloody, she is completely emaciated, and everything points to her having endured something horrific. Anna handles the case alone, while Ruiz feverishly searches for the killer of a couple who were brutally murdered. He is at an impasse because the only witness, Andreas Schaller, is mentally ill and refuses to talk. Joe is supposed to help get him to confess, when the young girl’s case takes a huge turn.
