The Allied bombers have reduced large neighborhoods of the city to rubble, and many Germans have found that the only way to manage is to dig caves under the debris. You and others who have chosen this way of life survive by digging through garbage cans to find whatever you can to eat, clothe yourselves, and heat your pitiful shelters.
One day, as you are making your rounds through the back alleys of Berlin, reeking from garbage, hungry, clad in rags, you are stopped by the police. They examine your stolen identity papers and conclude that you cannot be the person described on them. you try to explain that the life you have been leading has changed your appearance, that the picture is really you, the way you used to look. They don't believe you. They take you to police headquarters, where you are eventually identified as a Jew.
You are placed on a prison train and sent south to the concentration camp at Dachau.
