Schlag zu! (4x10)

Data di messa in onda: Giu 18, 1998

While training in his karate club, André is unexpectedly attacked by Olaf, a student. Olaf dies, although André only puts up a light fight. Inspector Kindermann then charges André with manslaughter and highway inspector André is suspended from duty. But Semir stands by his colleague. With the help of a doctor friend, he finds out that Olaf must have died from an undetectable doping agent. No coincidence - Olaf's death is a revenge plan by Unger, whom André once put in prison. Unger also manages to give André the drug that causes a heart attack when overexerted. A fight to the death ensues between the two.
