Ete and Ali are discharged from the army. Since Ete knows that his wife is having an affair, he doesn't want to go home. Ali tries to persuade his friend to stand up for himself and to kick the other man out. But since Ete obviously lacks courage, Ali himself goes into action and gets rid of the rival lover. At first, Mary and Ete seem to reconcile, but repairing their marriage won't work.

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.
