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.
