German sex comedy

"Bullenkloster" is the name given to the Ruhr miners' single home. Heinz Lenz has lived there since his divorce from Gisela. When he returned to the mine, he met his buddy Jupp again. Jupp persuades him to enter the ring once again. Only when Trudi promises him something, he agrees, but loses in the big fight. Through Jupp's mediation, he meets Gisela, who picks up their son. At first he only wants to see his son from a distance, but when he sees him he decides to start all over again.

Heiner works in a mine, drinks beer, and goes to bed with other women, except from his wife, because of his baby son and the neighbours downstairs. But she does not feel like giving up all the fun for so long.
