At the end of 1946, the Kuomintang army surrounded an independent regiment of the People's Liberation Army in southern Henan. In order to delay the enemy's offensive and ensure the safe transfer of the people, our intelligence workers decided to use false intelligence to confuse the enemy. Deng Yuanda and Ye Shuting were sent to Zhengzhou to perform this special task. Deng Yuanda successfully broke into the enemy. With the cooperation and help of Ye Shuting, he fought wits and courage with the spies headed by the Director of the Intelligence Department, Fei Siqing, and completed one task after another. Through continuous combat experience, Deng Yuanda has become more mature and eventually grew into an outstanding intelligence worker. And between him and Ye Shuting, the initial difficulty in communication has gradually changed to mutual understanding, trust, knowing each other, and love. At the last moment when they completed their mission and prepared to evacuate, Ye Shuting died heroically. After completing the mission, Deng Yuanda continued to move towards a new battlefield with their common ideals.
