Since the death of his wife, the samurai Nomi Kanjuro (Nomi Takaaki) seems to have become depressed. He refuses to go to the battlefield and is willing to abandon the dignity of a samurai. For this reason, Nomi became a samurai without a sheath and a sword. He wandered around with his daughter (Kumada Seiya), wanted by the lord (Kunimura Hayabusa) and hunted by assassins. During this period, even his daughter ridiculed him in every way. Nomi was eventually arrested, and the lord ordered him to make the young master, who was deeply saddened by the death of his mother, smile within 30 days, otherwise he would commit suicide. In the next 30 days, the two guards (Itao Soji & Emoto Tokisei) conceived all kinds of bizarre ghost ideas, but the young master's face was always full of worries. The deadline is getting closer and closer, and Nomi's life is hanging by a thread...
