Synopsis1In the summer of 946, the Kuomintang authorities assembled a large number of troops to attack the liberated areas. Zhang Zhijian, the platoon leader of a PLA unit, was ordered to lead the troops to intercept in a highland outside a town to cover the transfer of the main force. After five days and nights of bloody fighting, the situation is very critical. During the breakout, platoon leader Zhang, cook Lao Wang and correspondent Xiao Liu were all injured and captured. In order to find the food and military equipment buried by the People's Liberation Army, the head of the enemy's political work department interrogated Zhang Paichang and other three people with both hard and soft methods. But they are strong and unyielding. The enemy asked the traitor Qi Degui to seduce Lao Wang and Xiao Liu, but without success. Lao Wang eventually died of his injuries; In vain, Xiao Liu stabbed the enemy political director in the eye with a pen and made a heroic sacrifice. Zhang platoon leader's unyielding loyalty deeply touched enemy soldier Wei Jianji. With his help, Zhang Paichang escaped by luck and fled to the village to hide. The enemy threatened the villagers to take Zhang Paichang alive. Zhang Paichang could not bear to drag the villagers into trouble, so he stepped forward and was arrested again. The enemy played another trick, arresting Zhang platoon leader's mother and surrendering. However, Zhang's mother deeply understood the great righteousness, encouraged her son to be loyal to the people, and left the enemy at a loss. Soon, the People's Liberation Army captured the town, and Zhang Paichang survived. The leader awarded him a banner of "steel bones and iron tendons".
