On the eve of the liberation, our "underground" worker Liu Kehao successfully infiltrated the Northeast Station of the Nationalist Government's Military Statistics Bureau. He outwitted the "above-ground" military statistics agents, winning the trust of the station chief Xu Yinchu, and obtaining the city defense map of Shenyang, making remarkable contributions to the smooth liberation of Northeast China by our army. After the liberation, Liu Kehao and other "underground" workers transferred to the "above-ground" and entered the public security bureau to shoulder the important task of counter-espionage; however, Xu Yinchu and other Military Statistics Bureau spies were not willing to accept their defeat. They secretly went underground and continued to oppose the newly-born people's government. The two long-time adversaries are about to engage in another battle between "above-ground" and "underground"!
