Tony Hamilton, an ace pilot in the Air Force.

After distinguishing himself in a war in his homeland, he received an offer from his superior after the armistice: leave the military and become a teacher.

As he tried to embark on his second life, he was naive about the world.

The world had become steeped in anti-war sentiment. He endured cruel words like 'murderer' from his students, who further insulted his comrades who had risked their lives to protect their country.

Unable to tolerate this, he struck one of his students and was imprisoned.

It was a war, reignited, that pulled him from his cell.

Hatred, fear, injustice, absurdity.

And he becomes the devil of his homeland, of the enemy's land, the devil of the battlefield.
