Kommissarin Lucas S01E08 - Wut im Bauch

Inspector Lucas (Ulrike Kriener) is very concerned: her colleague Stefan Deuter (Thure Riefenstein) has been stabbed by the father of a boy whom Stefan had shot in self-defense. Stefan is in the hospital with serious injuries, and his colleagues fear for his life. Ellen is surprised when she learns that Stefan had handed in his resignation and she knew nothing about it. She is terrified when she learns from her colleague Boris Noethen (Michael Roll) that her younger sister Rike (Anke Engelke) is having an affair with the lawfully convicted violent criminal Robert Jandt (Ronald Zehrfeld). She confronts Rike, who sees Robert being treated and doesn't want any doubts about their love.
Then Anna Wiedemann (Henny Reets) becomes the victim of a serious violent crime and Jandt is strongly suspected of the crime. Anna Wiedemann is not yet able to be questioned, but traces found at the scene of the crime speak for themselves. The pattern of the crime is similar to the crime for which Jandt was imprisoned for five years, the act of violence against his ex-wife Jule Kieling (Kathrin Kühnel). Jandt, who protests his innocence, manages to escape from custody, taking Rike hostage. Inspector Lucas is beside herself with concern for her sister. She realizes that she can only save Rike and solve the case if she manages to break the persistent silence of Jule Kieling and Anna Wiedemann.
