On the eve of the victory in the War of Resistance, Liuba, which had been ravaged by the Japanese invaders for many years, was liberated. The New Fourth Army marched in, and the people of Jiangnan, who had suffered from the bullying of soldiers and Japanese aggressors for years, harbored a certain indescribable distrust towards those with guns. The soldiers of the New Fourth Army exhibited strict discipline and a rigorous style, quickly dispelling the local people's fears and integrating with them. Squadron Vice Leader Li Jin (played by Liao Youliang) developed feelings for Er Meizi (played by Tao Yuling) while recuperating at her home, getting close to her. When the instructor (played by Xu Linge) discovered this, he urged them to put aside their personal affairs. After the troops left, the local tyrant Liu Huzi tried to take Er Meizi by force, but she firmly resisted, always thinking of Li Jin. The troops received a rescue message from Er Meizi’s brother, Xiao Niu (played by Chen Donggang), and returned to Liuba to save her from her desperate situation. However, Li Jin prioritized the larger revolutionary cause, comforted Er Meizi, and returned to the front lines of the war, looking forward to the day they would reunite after victory.
