Zhao He, the company commander of the Kuomintang army, was captured in the Battle of Nanning. When he was about to receive the fare for his dismissal and go home, Tang Dacheng, the company commander of the Fourth Company, took him out of the prisoner camp as a "liberation fighter" and took him to the Korean battlefield. For veterans such as Chen Tianfang, Miao Quanlu, and Wang Baoquan of the Fourth Company, Zhao He was their former enemy. A war far away in a foreign country changed the fate of everyone. In Yunshan, in Changjin Lake, in Imjin River... In a foreign country, the war was raging. Both sides of the battlefield and this side were Zhao He's enemies. He had to carry the past and the present and survived the war with difficulty. In the hail of bullets, Zhao He and the Fourth Company grew up together. Zhao He gradually realized what a great army this team was, and the soldiers of the Fourth Company gradually accepted Zhao He. At midnight when the armistice agreement came into effect, when peace finally came, Zhao He and the soldiers of the Fourth Company witnessed history in front of the battle line.
