Zünd an, es kommt die Feuerwehr (1979)

A morality tale from the time of the Saxon Kingdom. The von Siebenthal volunteer fire department has nothing to do. When their local pub is in a very dilapidated state, but the landlord has no money to renovate it, the fire department tries to help out by setting fire to it themselves, but it doesn't quite work. They look for a new object to set fire to, the supposedly empty prison. But there is only one prisoner, who is heroically rescued by Captain Kaden.
