In the winter of 1941, the Japanese and puppet troops launched a massive attack on the New Fourth Army's Su-Yu-Wan base. In order to prevent the Jianghai Bank, which guaranteed the economic and financial lifeline of the base, from being hit and destroyed, the New Fourth Army decided to randomly relocate the Jianghai Bank. Just as another emergency relocation began, Lin Xiaotong, a graduate of the Yancheng Anti-Japanese University, reported to the Jianghai Bank with a letter of introduction from the military. The situation was critical, and President Luo Yizhong arranged for Lin Xiaotong to relocate without having time to understand the situation. After settling down, Lin Xiaotong found that the work of sorting out accounts and counting banknotes all day was far from his desire to fight the devils on the front line, and it was inevitable that he would have negative resistance. Faced with Lin Xiaotong's emotions, President Luo Yizhong and his wife Yuru patiently and meticulously did ideological work. With the help of President Luo and his wife, Lin Xiaotong quickly corrected his thoughts and made rapid progress. At Jianghai Bank, Lin Xiaotong also met an acquaintance of hers, classmate Xiao Nan. In smashing the economic blockade of the base by the Japanese and puppet troops, Xiao Nan accepted a difficult task to design the base's own anti-currency to resist the harassment of counterfeit currency and the destruction of the base's economy and finance. The task of designing the anti-currency is arduous, and the process of designing and issuing the anti-currency is also very difficult. However, with the encouragement of the president and the help of Lin Xiaotong, Jianghai Bank's anti-currency finally began to circulate in the base area. The difficult years of war tempered Lin Xiaotong's revolutionary will and witnessed Lin Xiaotong's love. In the arduous work of repeatedly transferring, collecting taxes from merchants in the Hexi region, and promoting anti-currency, love brewed in the hearts of Lin Xiaotong and Xiao Nan, two young people who were originally in tune with each other. Jianghai Bank received an order from the New Fourth Army Headquarters. Due to tight funds, the front line urgently needed a batch of anti-currency. The situation was urgent and the enemy was mysterious. The gradually mature Lin Xiaotong took the initiative to volunteer to serve as an escort mission with Xiao Nan and the guard squad leader. After avoiding the repeated pursuit of the Japanese and puppet troops, he was finally intercepted by the Japanese and puppet troops when he abandoned the shore and went to the ship. At the critical moment, Lin Xiaotong had an idea and disguised herself as a fierce woman. She successfully deceived the Japanese and puppet troops who came on board to search and successfully completed the task. It was another emergency transfer. In a hurry, Lin Xiaotong lost a backpack that he was responsible for. When he found out that a package of anti-Japanese currency he was responsible for was lost and he and Xiao Nan were trying to find it back, they were unfortunately chased by the Japanese puppet army. In order to cover Lin Xiaotong and protect the economic and financial lifeline of the base, Xiao Nan sacrificed his young life and died with the enemy. At this time, Luo Yizhong's wife Yuru died of dystocia during childbirth. The whole team, with great grief, Lin Xiaotong, led by Luo Yizhong, moved towards the new battlefield more resolutely.
