The traitor Zhigao Pu led the spy to the countryside, and Jiang Jie was unfortunately arrested and locked in a scum hole. In prison, she was tortured, and the ferocious enemy nailed a bamboo stick into her finger. In the face of torture, she proudly declared: "Torture is too small a test, bamboo poles are made of bamboo, and the will to produce party member is steel." Qiu Lai's winter is over, and it's almost the end of the year. The national revolutionary situation was excellent, and the Kuomintang authorities began to release the atmosphere of peace talks after being hit hard. On Lunar New Year's Eve, all the friends in Zhazidong held a special party. What is more gratifying is that the underground guerrillas got in touch with them. In order to show "sincerity" of the peace talks, the enemy released some political prisoners on the pretence, and party member Liu Siyang of capitalist family was one of them. On the second night after he was sent back to Liu Mansion, a man who claimed to be surnamed Zhu sneaked into the Liu family, saying that he was appointed by the district party secretary to understand his performance in prison and asked him to report the underground party in prison in detail. Just when I became suspicious of this man, I sent someone to send information and exposed the true face of this disguised spy Zheng. Liu Siyang was arrested and put into another prison "Bai Mansion" before he could be transferred. After the deception failed, Zheng pretended to be a journalist sympathetic to the revolution and entered the scum hole. He tried to venture into the secrets of the underground party in prison. Yu Xinjiang and others saw through his disguise and got rid of this insidious spy by the hand of the enemy. The people's liberation army is approaching Chongqing, and the underground party is preparing to organize prison riots. Party member Hua Ziliang, who has been crazy for many years in Bai Mansion, has been in contact with the Party organization in prison. At the same time, Xu Yunfeng dug a secret passage in the cellar with his fingers and chains. When the People's Liberation Army invaded Sichuan and was about to liberate Chongqing, Xu Pengfei and others climbed over the wall and secretly killed Xu Yunfeng, Jie Jiang and Cheng Gang in advance. On the night when Xu Yunfeng and others were killed, there were riots in Zhazidong and Baigongguan at the same time. Some comrades, such as Liu Siyang, died, but more comrades finally rushed out of the magic cave accompanied by the rumbling guns of the People's Liberation Army to meet the glorious dawn!
