She is engaged to Richard, a Jew from Neuss, but it is not he who is accompanying her, but the Italian Giuseppe Buonomo, who dies in the collision. The shop girl Lisa from the Magnus department stores’ is given the task of providing the injured woman with clothes as she has lost everything in the accident. But Carla is already pretending to be Mrs Buonomo. What is she trying to hide?
