Set towards the end of World War II, Kaede Itakura, who leads kindergartners, and Mitsue Nonomiya, who enjoys music, persuades the parents at the school to take their children out of Tokyo. They seek shelter at an abandoned temple in Saitama while Tokyo is bombed.

Starting in 1970s Hokkaido, the film charts the moral descent of Detective Moroboshi over three decades, the young cop quickly gets a bit too cozy with the other side of the law when his senior colleague Murai teaches him the ropes and ruts of the police business. Soon, he swaggers and rants through the streets of Sapporo a lean, mean, sex‐crazy bully, indistinguishable from a yakuza.
