Mimura Shinokocheng (Kimura Takuya) is an ordinary junior samurai. His job is to test the poison for the clan master. The prepared food is eaten by the tester first, and only after confirming that there is no adverse reaction will he give it to the host. In a poison test, Shinagocheng lost his sight and lost his eyes, and his fate turned sharply down. fortunately, with the help of his beautiful and virtuous wife Jiashi (Tan Li), he faced life again. However, the Mimura family lost their source of livelihood, and in order to make ends meet, Gasai asked his superior Tanjima (Sakata Sanjin Goro) to intercede with the lord, hoping to keep half of his salary. But Shimada used Shinoko's salary as a threat to force Gasai to commit himself to him. When Shinoko learned that he could not accept the truth, he gave up his wife and decided to fight to the death with Shimada to save the dignity of the samurai, which is more precious than life.
