Tracking the Tiger's Den

In the early 1950s, in a northern city, the city that had just been liberated was in dire straits. International hostile forces and domestic secret agents are unwilling to accept their defeat and are always ready to carry out sabotage activities. Scout Li Yonghe (played by Zhao Lian) returned from reconnaissance, and the director of the reconnaissance department Chen Huiyuan (played by Yin Zhiming) assigned him a new task. Li Yong and Maoxue followed a suspected woman riding a donkey, but were unexpectedly tied up by a group of gangsters who suddenly appeared. The fake spy certificate in his hand saved him. After being arrested, agent Huang Yunmeng (played by Li Jie) confessed: the hidden list was handed over to agent Cui Xizheng (played by Li Jingbo) disguised as a warehouse manager. Li Yonghe broke into the warehouse as a spy and learned from his apprentice that the list of spies might be hidden in an ancient painting scroll. Unexpectedly, the cunning Cui Xi Zhengji transferred the list. After a battle of wits, he finally found the list.
