Overview:For thirty years, Karl Achilles has been working at the chemical collective in Bitterfeld. But now his last day as a master at the plant has come. He is about to retire; even if Karl, who finds ending his working life difficult, wanted to stay on, it would not be possible. Karl’s colleagues have arranged a farewell dinner for the retiring master at an outdoor restaurant. But on his last day of work, before the farewell dinner, he meets all sorts of people: both colleagues and people, who do not work at the plant. A mosaic of the biography of a person who found fulfilment in his work and now has to look for the meaning of his life anew.
