A Case for Two - Season 11 (1991)

Young Michael Hude is arrested for the murder of a department store security guard. He admits the murder, but his mother Angelika is sure that he is lying and asks her friend Dr. Franck to defend him and to try to find out the truth. Although Michael states to have killed the guard in a fit of anger, Matula discovers that he had been tailing the victim since several weeks.

Young prostitute Hanna wants to leave her job to marry her boyfriend Walter: after having admired Dr. Franck at a trial where he successfully defended another prostitute who killed her violent procurer, she asks him to deal with her own procurer to free her from him. Matula takes care of the dealing and everything seems to go well, until one night Hanna is found killed in her home and Matula is arrested because he was seen coming out from her home shortly before.

While driving to theater, Dr. Franck and Matula rescue young Bruno Maschke who is trying to jump off from a bridge. Maschke just came out from prison and was abandoned by his wife Helen, who refuses to meet him again. Rainer manages to organize a meeting between him and his ex wife, but when Maschke reaches Helen's home he finds her killed: as main suspect, he hides himself at Dr. Franck's home.

A Turkish girl is murdered in Frankfurt and her father, Mr. Mustafa Tüyen, asks Dr. Franck to defend his son Ismail: the boy is not yet accused, but the fact that he had publicly threatened his sister for her too much Western-like attitude risks to focus suspicions on him. Matula starts his investigation with the girl's ex-boyfriend and discovers that she recently had a baby.

Mr. Düllmann catches a thief in his villa and shoots him dead. The thief's wife, Mrs. Seiffert, doesn't believe that her husband would have ever done anything similar and asks Dr. Franck to defend her at the trial: she wants to prove that her husband was purposely murdered.

Dr. Franck is appointed by the court to defend Thomas Spengler, who sits in prison since months: he was caught while delivering an extortion letter to a supermarket, threatening to poison food, and a woman just died of food poisoning. The man states that he was only asked to deliver the letter, without knowing what it was about, but the court is determined to show his guilt.

Matula has been hired by young Tanja Wilhelms, who wants to know if her husband betrays her. When he confirms it to her, she spends the whole night out drinking and meets young photographer Sascha Rentrop, who once worked for her husband, and who brings her at his home. After having spent the night together, the morning after Tanja finds Rentrop killed. But she has drunk so much that she cannot remember anything of that night, so she calls Matula for help.
