For thirty years, Shingo Shimazaki worked with the terrorist organization Revolutionary Army of the League for Economic Liberations.

He tries to integrate into this new everyday life, but some seemingly ordinary tasks are difficult for him, and his Japanese is noticeably unusual. He tries to cope with all of this using the skills he acquired through military and espionage training. Some people help him, while others try to thwart his integration.
