Man Müßte Nochmal Zwanzig Sein plot
Friedrich Hoffmann is seventy years old, a well-to-do person - he owns a chocolate factory - and is surprised to learn that he has a twenty-year-old granddaughter named Susanne Menzel. To get to know her better, he asks his cousin Dr. Paul Degenhard, but when he bounces back he loses the piece of paper on which her name and address are scribbled. Without realizing it, he hires her as a secretary, after which the misunderstandings continue: the greedy heirs believe that Hoffmann has a mistress, but at a family celebration everything turns out on its feet.
