A group of Okinawan high school girls are drafted as nurses during the American invasion of the island. As the enemy army advances further, the situation for the girls becomes increasingly desperate as food and shelter run out and the number of injured climbs, leading to the film's tragic finale.

Three bank robbers, Eijima, Nojiri, and Takasugi, flee the police and escape into the mountains. At an inn high in the Japanese Alps, Eijima and Nojiri encounter a young woman and her father, as well as Honda, a mountaineer. The inn folk do not realize their guests are wanted criminals and the visitors are treated with great kindness. Honda volunteers to lead them over the mountains, but Eijima's paranoia endangers all of them as they make the perilous trip.

In this government-suggested sequel, Sugata again grows as a judo master, and demonstrates his (and by extension, all Japanese) superiority to the foreign warrior.
