Sohnemänner plot
A tense situation within the family is rekindled in Grandmother's old age. She is picked up by her grandson Uwe from her rest home in Hamburg, where she was taken by her son Edgar. Uwe takes her to the Black Forest, to the house of his rich mate. Edgar then immediately jumps on his motorcycle and drives there. A subtle power struggle breaks out between father Edgar and son Uwe, who couldn't stand each other anyway. Uwe always believed that Edgar had simply 'banished' his mother. But it is only when the grandmother becomes ill in her new environment that the two ruffs come together for the first time.
