Robert and his colleague Kay clash with his lawyer Rico Heilmann during the arrest of a young violent criminal. While Kay goes clubbing after work, Robert goes home to his daughters. He is woken up early in the morning: Kay was murdered that night. She was shot with her own service weapon in an abandoned backyard. Why did she have drugs with her? And why does the social worker Theresa think that Kay worked as a nurse? When Robert finds Kay a threatening message from the youth who was arrested the day before, he seems to lose control. His behavior means that department head Katharina has to temporarily suspend him from duty.
