The story begins in occupied Japan just after the end of WW2, where former soldiers get involved in black market with all the consequences which you can imagine. After a fierce gunfight with the police, the hero is arrested and sent to jail, where he will have to learn how to survive. I have never seen any prison film from the Rising Sun Empire yet; that's the first one. Of course it's pretty violent, as you can expect from a Japanese crime flick. And Ando Noburu is of course at his best here, like a fish in the water.
