It's the time of World War I. When the Germans lost the battle of Tsing Tao thousands of them are deported to Japan as prisoners of war. The storyline follows a couple of those men. At first they're brought to a camp where they are treated badly and are looked down upon because they didn't have the courage to kill themselves. After two years they're brought to a new place called Bandou. There the camp director follows another policy and lets the Germans have as much freedom as possible. Despite many opposing voices both Japanese and Germans learn to realize that the respective others aren't barbarians.
