The Uchidas need to leave their home to go to an internment camp. It is WWII, and there is suspicion that Japanese Americans will not be loyal to the United States, and support the Japanese cause.
The Uchidas go to the First Congregational Church of Berkeley, whey they, along with many other Japanese Americans, will be sent by bus to the nearest internment camp.
When they arrive at the camp, there are armed guards, army vehicles, and barbed wire fences. It is like a prison.
When the "evacuees" are called to the mess hall, they go down stairs to a cramped basement with many people, and they are served boiled potatoes, canned sausages, and butterless bread.
When the Uchidas get their bags back from the guards, they decide to make tea in their "apartment", which is really a horse stall. Yoshiko goes to the washroom to get water, and discovers there are no doors for the stalls or showers.
Yoshiko and Kay run into some friends from college who give them dried plums. The Uchidas eat them, thinking about the luxuries they will not be given at the camp.
