Episode list

The son of a banker sees his life in danger because of a drug deal in his past. Renz investigates while Matula protects him. After a while is becomes clear that it's not about the drug deal, but about something else he did at that time.

An African comes into Renz' bureau and tells him about a German electronic company that produces parts for weapons used in Africa. Later, he supposedly kills the boss of this company, but Renz has serious doubts about that.

A man is released from prison and after his release he is contacted by the mother of the woman he killed. Soon after that, turbulent events rapidly unfold.

After having obtained a mild sentence for a gang of burglars who robbed a casino and never made the loot be found, Dr. Renz announces to Matula his intention to retire and move to a farm he is buying in Italy. But when the loot is found in Renz's home and several evidences point to him, he is arrested. Matula finds for him a young lawyer, Dr. Rainer Franck, whom he had met shortly before at a motocross event and who had just stolen his girlfriend.

While Dr. Franck is arranging his new practice, sketchy dude Heinz Rose visits him pretending to know the address of Berthold Kramm, a client of Dr. Renz, and threats him with a gun. Kramm is curiously linked with the first job Rainer has got for Matula: to guard the home where Renz's client once lived and now is owned by a young woman who has received some inexplicable threats.

Mrs. Irma Westermühl rushes terrified at night to Dr. Franck asking him help with her husband Alfred, who is threatening to commit suicide in his workshop, but right when they reach him the workshop blows up. But when Dr. Franck brings Mrs. Westermühl home, he notices that her husband is alive in the house: surprised, Alfred Westermühl kidnaps him and locks him in the cellar. Matula has then to search for his missing boss.

Alma Becker, a former girlfriend of Dr. Franck, visits him at night wounded and shocked: her boss has just been killed and someone tried to kill also her as being a dangerous witness. Dr. Franck decides to help her while hosting her at home and asking Matula to investigate.

Herbert Lersch disappeared after having gone to a job interview. Some days later, his wife Friedel decides to ask Dr. Franck and Matula for help. Their investigations show immediately a link between this disappearance and a mysterious murder case of a businessman some days before.
