Vienna, 1937, on the eve of the annexation of Austria into Nazi Germany. The young and inexperienced Franz Huchel begins to learn about both the joys and hardships of life by working as an apprentice to the mutilated war veteran Otto Trsnjek in a small tobacco shop, where he meets the famous psychiatrist Sigmund Freud, a regular customer, who will become a valuable friend in times of chaos and uncertainty.
Former detective Brenner has become an ambulance driver and finds himself, much to his dismay, caught up in a war between two rival first aid organizations.
It all begins with a mistake, an error with serious consequences: in a hospital the new-born babies of an Austrian couple and a Turkish family of immigrant workers are mixed up and go home with the wrong parents. By the time the mistake comes to light, it emerges that the Turkish family, including the baby, has been deported. The despairing Austrian couple begins a confusing odyssey through Turkey in order to track down the unsuspecting family to their native village. But they are not at all convinced that the babies have been mixed up. It is decided that the only way to know for sure is to have a blood test done. It is decided that the blood work is done in Vienna due to the better medical resources, but that will be far from simple. It will involve an illegal smuggling of the Turks across the Austrian border.
