[1][2] Due to a malfunction in the fictitious nuclear power plant Markt Ebersberg near Schweinfurt, Bavaria, an MCA occurs and the whole area is evacuated extensively by the authorities.

She has to take care of her younger brother on this day since the mother is in Schweinfurt because of business matters; exactly where the disaster has occurred.

During the trip, the teenagers learn about the events on the radio, but they do not really understand - until they arrive in Schlitz, where Lars' mother drags him out of the car and tells the others that her son can not take them with him because he has to flee with his family.

In the midst of the panic, the two finally receive a call from their mother: she does not want the children to go to the cellar, because the radiation reaches them there, but flee to Bad Hersfeld with the neighbors, from where they take the train to Aunt Helga in Hamburg.

Since the motorways are crowded, many others want to flee with the trains, so Hannah has to pay attention to the little daughters of the family on the platform since the parents still have to fight their way through.

In Hamburg, where Aunt Helga lives, Hannah goes back to school but remains isolated there because her radiation damage is too obvious because of her baldness and the people avoid her.
