The story happens in the Korean War (1951-1953)In the autumn of 1952, the American troops launched a large-scale attack by the border between South Korea and North Korea while the Sino-American negotiation at Banmen Dian adjourned. The American representatives meant to steer clear of the futile negotiation by dispatching their troops to occupy Shanggangling Mount and Wesheng Shan Mountain. In that case, Zhang Zhong Fa, a company commander of Chinese Voluntary Army, led his troops to guard Shanggangling Mount. In an extreme difficult situation, they held on to guarding the position in 24 days and succeeded in dragging the force of the enemy so that the Chinese main forces were in an advantage situation to defeat the enemy. The American were forced to resume the negotiation and sign their names on the armistice paper.
