An unforgivable summary of the plot

In the 13th year of Meiji (1880), a man bent over to reclaim wasteland in Hokkaido, Japan. This man's name is Shi Bingwei (Ken Watanabe), and in 1870, his nickname is "Shi Bingwei's executioner". After the Meiji Restoration, the figurehead of the shogunate went to a wild place in anonymity, married a gentle woman, gave birth to a lovely child, and enjoyed an instant happiness that had never been seen in his life. He made an agreement with his wife that the killing knife would be sheathed forever, just for the rest of his life. However, things are unpredictable, and his wife died unfortunately. On the barren land in the northernmost part of Japan, 10 soldiers and guards with young children struggled to survive alone. On this day, Ma Chang's old friend Jin Wu (Akira Emoto) made a surprise visit to persuade ten soldiers to return to Jianghu as bounty killers. It turned out that the beautiful prostitutes in the town were ruthlessly disfigured by ruthless guests, but the authorities had no intention of pursuing them. Her customers were angered, and everyone paid a reward for the owner to avenge the woman. Unable to resist the persuasion of the racecourse, and in order to improve the children's present situation, ten soldiers nodded and agreed. At that moment, he broke the agreement with his wife and took a step towards an unknown and dangerous fate. Waiting in front of the ten soldiers and guards is the absolute dominator of the town-the police station, Akazo (K-1). Dashi is headstrong, arrogant and cruel, and has no mercy on bounty killers who dare to attack. In the dangerous fight, ten soldiers finally pulled out the long-sealed sword. For a little son who has no food or clothes? For evil women who have been brutally abused? For an old friend who has been a good friend for many years? Or for yourself? Ten soldiers with all kinds of lives, this time they broke with the troubles that haunt the whole body!
