Josef Nötzli is a shy and somewhat awkward man. He has been working as an accountant in a chemical plant in West Berlin for 26 years. But Nötzli originally comes from Switzerland. Nötzli started out as an accountant and remained in this position. Due to a misunderstanding, Nötzli suddenly makes someone else's career. At last, Nötzli is able to put his knowledge and concepts into practice. With his ideas, he quickly steers the badly damaged company back into the profit zone. But it is precisely at this moment that Nötzli's high-flying career comes to an abrupt end: the mysterious misunderstanding comes to light and Nötzli is dismissed from his post, accused of deliberately obtaining a position by fraud. Together with his colleague Neubauer, Nötzli ends up back in the accounts department. Now nothing can keep him in the company. He leaves the chemical plant with his friend Neubauer. But is this farewell final?
Josef Nötzli has swapped his job as an accountant for a chicken farm in Switzerland. He wants to be just as successful as his twin brother John, who he believes runs the Aurora Hotel in Berlin. In reality, however, John is one of the biggest underworld bosses, and the "Aurora" is Berlin's most famous brothel. When John suddenly dies in Bangkok, Max, John's partner, wants to prevent anyone in Berlin from finding out about John's death at all costs. First, with Josef's help, he has to get the black money from the bank. Under the pretext of having to accept the inheritance, Max brings Josef to Berlin. Once there, of course, everyone believes that Josef is John, the feared underworld boss, and so a maelstrom of confusion ensues.
