1944, in the depths of World War II. Toyomatsu Shimizu is a completely typical barber from a remote sea-side town who lives frugally but happily with his wife Fusae and their five-year-old son. Eventually, though, the army beckons and he is drafted. One day an officer on the battle-field orders him to kill a captive U.S. soldier. Although Toyomatsu lacks the spirit to kill the man, and only wounds him in the arm, the victorious U.S. soldiers will not accept this, and Toyomatsu is arrested and tried as a war-criminal. And he receives the cruelest sentence possible...

Even though Gennosuke and Oboro are from rival ninja villages, they are secretly in love. At an annual conference with the Lord, it is dictated that a competition--a fight to the death--will take place between the five best shinobi from each village. Gennosuke and Oboro's love is made even more impossible when they each got picked as the leader of the five to represent their respective villages.
