Ogami (Tomisaburo Wakayama) and his son Daigoro (Akihiro Tomikawa) have been following the Demon Way for five films, chasing the elusive Lord Retsudo (Minoru Oki) of the villainous Yagyu clan who was responsible for the murder of Ogami’s wife and his subsequent framing for treason. The Demon Way is never easy, and Ogami has committed himself to following it to its conclusion, but recent encounters have broadened a conflict in his heart as innocents and seekers of justice have died alongside guilty men and cowards. Lone Wolf and Cub: White Heaven in Hell (子連れ狼 地獄へ行くぞ!大五郎, Kozure Okami: Jigoku e Ikuzo! Daigoro) moves him closer to his target but also further deepens his descent into the underworld as he’s forced to confront the wake of his ongoing quest for vengeance.
Ogami and Daigoro have made it to Snow Country, meanwhile Lord Retsudo is receiving a dressing down from a superior over his total failure to eliminate the Lone Wolf or his Cub. It seems Ogami has already despatched all three of Retsudo’s sons, and so now Retsudo pledges his daughter, Kaori (Junko Hitomi), skilled in the use of daggers and every bit as fine a warrior as her defeated brothers, in the mission to end the Ogami threat.
Things do not go to plan and Retsudo is forced to approach his one remaining son. An illegitimate child born to a concubine, disavowed, and hidden away in the mountains, Hyoe (Isao Kimura) is not well disposed to his estranged father’s request to save the Yagyu clan to which he feels only rage and resentment. Sending his father away, Hyoe nevertheless decides to take on Ogami in the hope of embarrassing the Yagyu by taking him out first. Possibly having spent too much time alone, Hyoe’s plan involves a number of strange rituals beginning with resurrecting three of his men as emotionless (yet intelligent) zombies meant to terrify Ogami and his son into submission.
Throughout the series, we’ve seen Ogami’s world darken as the straightforward missions of eliminating corrupt lords eventually gave way to more morally dubious assignments with the tragic story of Oyuki and later the assassination of an entire family in order to preserve the legitimate arm of a historical clan. Along the way, Ogami has met “true samurai” and villainous cowards, but his encounters with honest men and women have only served to shake his heart as he guides his young son onwards bound for hell by way of death or violence.
The pair have never been afraid before, but Hyoe’s plan hinges on pushing Ogami’s mind into those dark places, preventing him from fighting back against his supernatural soldiers. Death has always surrounded them, but the price of Ogami’s vengeance is brought home to him when Hyoe’s forces unceremoniously wipe out the entire population of an inn where Ogami and Daigoro are staying whilst hovering in some nearby trees to remind them that this is all really their fault and the longer they keep on down this path, the more the innocent will suffer. The zombie trio threaten to destroy Ogami’s human emotions – joy, sorrow, pleasure, and anger, leaving him only with fear. Unbowed, Ogami faces Hyoe but the pair have more in common than they thought and so round one ends in a stalemate.
White Heaven in Hell, though not intended as a conclusion to the series, neatly brings things full circle as Ogami visits his wife’s grave, recalling his familial tragedy and reinforcing his bond with Daigoro. All of the films have, in some way, dealt with functional and dysfunctional family, each commenting on the unusual relationship between Ogami and his son. Finally meeting face to face, Retsudo takes Ogami to task for the loss of his children which Ogami throws right back at him – after all, all he did was defend himself against a threat Retsudo himself instigated. Ogami eventually tells him that he hopes Retsudo becomes so lonely that he goes completely mad. Retsudo’s pointless manoeuvring has cost him dearly in the loss of each of his legitimate children, eventually forcing the acknowledgement of his illegitimate son and daughter whose hatred of him also leads to their undoing. So great is Hyoe’s loathing of the Yagyu, that his last ditch attempt at revenge is in trying to convince his own sister, Azuma, to bear his child and create a new line to finish them off once and for all.
Kenji Misumi declined to return for this instalment, claiming the series had become too much like a Western which is a little ironic as White Heaven in Hell leaves the arid deserts behind for the frozen ice plains of the north. Yoshiyuki Kuroda, making his first and only contribution to the series, had a strong background in horror cinema which might explain the sudden appearance of the supernatural elements in what has been, up to now, a fairly grounded exercise even if somewhat outlandish. This is also the only script with which original creator Kazuo Koike was not not involved and bears the least relation to the then ongoing manga. Still, the action is undoubtedly innovative as the baby cart’s wheels are swapped for skis and Ogami faces off against an entire army of enemies on a snow covered hillside. Kuroda sticks more closely to Misumi’s aesthetic than Saito had done though steers away from the painterly cinematics in favour of showcasing the snow covered terrain, driving Ogami deeper into hell as his heart freezes over but denying him the vengeance that has become his life’s work. White Heaven in Hell is the last outing for Ogami yet refuses to close the circle, his quest may be a never ending one, plunging both himself and his son into an inescapable cycle of violence and regret as the Demon’s Way stretches on endlessly towards an uncertain destination.

Conflicted as he was in his execution of a contract to assassinate the tragic Oyuki in the previous instalment,
