In the early spring of 1945, the Japanese warlords received an order to evacuate Manchuria, China after the bombing of Tokyo. All the biochemical research materials of the Hako Ichi unit were withdrawn to Japan, and everything that could not be taken away had to be destroyed. Lieutenant Colonel Kato (played by Choi Young-joon) refused to accept it and refused.If you are willing to "introduce people" to the experiment, you will soon produce the strongest species...

Yin Caiyu and her father Yin Zhong (played by Zhao Hanzhe) came to the North Korean capital from Manchuria to inquire about the Japanese painter Sakamoto.Japanese police whistles were heard in the distance, and the secret newspaper office of the Independence Army was uncovered. The Japanese police arrested the reactionaries mercilessly and beat them severely before forcing them to join the army as punishment.At this time, there was another North Korean, Zhang Taishang, who was locked in a secret room of the police station and was beaten severely by police officer Ishikawa. Zhang Taishang was forced to find his lover Mingzi for him. He had to find his lover Mingzi for him before the cherry blossoms scattered, otherwise Jin Yutang's pawnshop would be confiscated and Zhang Taishang would be confiscated by the army!

Jang Taesang returned to Jinyutang and told the housekeeper Na Yuesi (played by Kim Hae Sook) and the shopkeeper Uncle Gapyeong (played by Park Ji Hwan) about looking for Myung Ja.All the comfort women girls were found, so spies were immediately hired.Zhang Taishang went to Guangyue Bar and was followed by someone. After a scuffle, his hat fell off and he discovered that the person was a woman. Zhang Taishang was immediately attracted. Yin Caiyu expressed his intention to come, but Zhang Taishang accidentally said the wrong thing. Yin Caiyu slapped Zhang Taisang and called Zhang Taishang trash.Tong, Zhang Taishang is not angry because he lives in such a dirty way.

Zhang Taishang went to Guangyue Bar to find Quan Jundu (played by Wei Gujun), the son of a pro-Japanese wealthy businessman. He was the only one who had the ability to elope with a geisha, but Quan Jundu said that his son had abandoned him and did not know where she was, so he invited Zhang againTaishang supports the Independence Army, but Zhang Taishang lives in vain to save the country and the people.

Zhang Taishang returned to Jin Yutang. The spies have arrived, and one of them is the woman who slapped him!Yin Caiyu felt that she was being suspected and simply refused to take the case. Zhang Taishang saw that Yin Caiyu fell out and quickly told her that he was the only one with Japanese connections who could help her find her mother!At this moment, the Manchurian military medical unit hid in Wengcheng Hospital and secretly conducted a human experiment again. One of the two subjects died, but the other mutated into a monster!
