Frank Steier is finished - a wreck. When he finds himself on a bench in the city park after another night of drinking, he witnesses the murder of a jogger. His pursuit of the perpetrator ends miserably. Two surprises are waiting for him in the police station: his boss introduces him to the brash detective inspector candidate Linda Dräger (Alwara Höfels), who is supposed to be at his side, and at the same time he is taken away from the murder case as a witness. But that doesn't stop Steier from investigating. The fact that he didn't catch the perpetrator gnawed at his vanity. He finds out that the victim was a fellow teacher of his ex-wife. She is briefly shocked by the murder, but also uses the meeting to tell him about her young lover Lars. Not a good day for Chief Inspector Steier.
He secretly observes the new man in his former wife's life and discovers some inconsistencies. At the same time he is summoned to a mysterious dead man. Apparently there is a connection between the dead man and his ex-wife's lover - in addition to Joachim Król, other roles include Peter Kurth, Alwara Höfels, Jenny Schily, Volker Bruch, Gerd Wameling and Gerrit Jansen. The script was written by Hendrik Handloegten and Achim von Borries, who also directed. Filming took place in spring 2013 in and around Frankfurt.
