A Case for Two - Season 13 (1993)

Mrs. Julia Lohring asks Dr. Franck for help: her daughter Christine is going to marry young Stefan Reichner, but she doesn't trust him and she knows he has a relationship with another woman and wants to prove it to her daughter. Matula manages to come in contact with this woman, Angela Winter: she is terrified because someone is threatening her and asks him for protection.

A former client of Dr. Franck is killed at night and the police files the case as a settling of scores. Rainer is sure that the boy had left the crime and wants to help his mother to find the truth: he and Matula investigate about young Heike Landers, who was unwillingly involved in the shooting and who is recovering from the injuries in a clinic. Her involvement seems initially a pure casualty, but now someone is threatening her as a dangerous witness.

While leaving his accountant's office, Dr. Franck finds a dead man lying in the lift. But when, after having called the police, he and the accountant go back to the lift to check, the corpse is disappeared. The day after the police finds a dead man in the building's garage and Rainer recognizes him as the man of the night before: incidentally, the man accused for his killing is right asking him for defense.

Businessman Kleinert is kidnapped and his wife asks Dr. Franck to take care of the delivery of the ransom money the kidnappers asked for. During the delivery, Matula follows Rainer unaware of him and discovers that the money never reached the kidnappers but was thrown in an abandoned villa.

Young painter Marianne Sprenger, who lives in Sicily, comes back to Frankfurt after the death of her father and discovers that the gold he had collected is not to be found.

Max Wölke suspects that his grandson Martin stole his money. Some days later Martin is found severely injured: his father, serving for a robbery, escapes while visiting him at the hospital, seeking a revenge against his father-in-law, whom he considers responsible for what happened. Also the police believes the same and arrests him, and he asks Dr. Franck for defense.

Mr. Egon Manz wakes up in a hotel room after a night out with friends and finds a dead prostitute in his bed. His friend Reinhold Beckert calls immediately Dr. Franck, who persuades him to go to the police: unfortunately, due to heavy drinking, Manz cannot remember anything of that night and so he is arrested. Matula has got to investigate to prove his innocence, while Dr. Franck takes care of saving his client's marriage.
