In 1941, the international situation was turbulent, and there was even undercurrent in China, and a storm was about to sweep the ancient land of China.At this time, the special envoy of the International Anti-Fascist Alliance visited China and held a secret meeting with representatives of the Kuomintang and the Communist Party.The Wang puppet counter-revolutionary regime was moved when it heard the news, but eventually lost the opportunity and returned in vain.At the same time, a military intelligence station was destroyed. After a torture interrogation, it was learned that the intelligence of the Wang puppet operation was leaked from the inside.As a result, five people including Li Ningyu (played by Liu Weiwei), Gu Xiaomeng (played by Zhang Xinyi), Jin Shenghuo (played by Zong Ping), Wu Zhiguo (played by Tian Yu), Bai Xiaonian (played by Hu Haifeng), etc. were successively locked up in the mysterious and terrifying Qiuzhuang.In the next 88 hours, they face not only various ruthless tortures, but also the threat of death.Who is the "old ghost" who leaked intelligence?
