Since the death of his wife, the samurai Nogan Kanshiro (Nogan Longming) seems to have become depressed, refusing to go to war and willing to abandon the dignity of the samurai. To this end, Nagi became a samurai without a scabbard and a sword, and he wandered around with his daughter (Kumada Shengya), wanted by the lord (Komura Falcon) and hunted by the killer. During this period, even his daughter ridiculed him in every way. Nobi was finally caught, and the lord ordered him to laugh at the young master who was deeply grieved because of his mother's death within 30 days, or he would commit suicide by laparotomy. Over the next 30 days, the two guards (Banwei Chuanglu & Ben Shengsheng) came up with all kinds of strange ideas, but the young master's face was always clouded with sadness. The deadline is getting closer and closer, and the situation is in danger.
