While most of the prisoners are near starvation and have uniforms that are in tatters, King eats well and and has crisp clean clothes to wear every day. Included among the prisoners is the American Corporal King (George Segal), a wheeler-dealer who has managed to established a pretty good life for himself in the camp.
