Irrlicht und Feuer (1966)

Jürgen Fohrmann works as a hauer underground. In the course of the coal crisis, his mine closes - he loses the work. In this mood, his wife's prosperity thinking gets on his nerves - his marriage threatens to break. The dismissed coal buddy applys, first becomes an auxiliary worker, but then receives a job in an automated operation of the electrical industry and believes to have socially risen through this "clean work". Fohrmann quickly realizes that wearing a "white coat" is only seemingly better than the arduous work in the pit and understands that he can no longer stay out of the work struggles of the buddies.
