Detectives Max Ballauf and Freddy Schenk must solve the murder of the head physician of a psychiatric clinic. Ballauf himself is currently undergoing treatment: a trauma he thought he had overcome resurfaces with full force. After shooting his colleague Melanie Sommer during an operation, he is plagued by nightmares and guilt. Sometimes he believes he sees the dead woman before him. He can't talk about it, not even with his partner Freddy Schenk. The atmosphere within the team is correspondingly tense. During their investigation at the hospital, a patient catches Ballauf's attention. Julia Frey claims she is being held against her will in the clinic's closed ward. Deputy head physician Dr. Koch, however, points to Julia's emotional instability. But Max suspects that Julia's cry for help might be justified. [Köln]
