The flames of war are burning in southern Xinjiang, and loyalty is forged with blood. In 1979, the Sino-Vietnamese self-defense counterattack began, and artillery fire continued on the Western Front battlefield, destroying lives. The Tiger Company was ordered to go on an expedition, facing the dangers of jungle ambush, the cruelty of clearing tunnels, and the difficulty of long-distance raids, and built a barrier in southern Xinjiang with their flesh and blood. Company commander Zhou Wei is tough on the outside but soft on the inside. On the one hand, he is calm and decisive in commanding the battle, but on the other hand, he is guilty and distressed for the casualties of his comrades; the recruit Sun Hao has grown from an ignorant boy with trembling hands who dare not shoot to a strong warrior who can stand alone; the nurse Zhang Fang loses her greenhouse squeamishness under the gunfire and protects the lives of her comrades with a gentle hand. The war is ruthless, taking away the brothers who fought side by side, but it cannot take away the faith to protect the country. The years have left traces, remembering the bloody journey, and even remembering the deep love of life and death. The panoramic view presents real war history clips such as the rescue of overseas Chinese, the attack on Lao Cai, and the decisive battle in Sabah. It not only shocks the grand battle scenes, but also touches the delicate emotions. If you understand the persistence of the Tiger Company, you can understand the responsibility and responsibility of the Chinese soldiers.
