EPISODIUM
The lawyer Rieger is contacted by telephone and forced to hand over a gun to a dangerous prisoner, a certain Günter Hausmann, so that he can easily escape. The mysterious telephone operator warns Rieger that his wife has been taken hostage and will be killed if the request is not fulfilled. The lawyer agrees but, before delivering the weapon, he empties the magazine. A few days later Derrick is informed that Hausmann killed a prison guard during his escape.
