"Red Channel" tells the story of how, after the Sixth National Congress of the Communist Party of China held in Moscow, in order to ensure the smooth return of the top leaders of our party, the underground members of our party paved a red channel with their lives and blood in just ten days in desperate situations. The super agent Wu Quan, played by Liu Ye, was ordered to protect the mysterious No. 9 leader to pass through the channel smoothly. At the same time, the Nanjing government also sent Zhou Mohan (played by Liu Bin), who had sinister means, to kill the No. 9 leader at all costs. For a time, in the border town, various forces secretly gathered, and the town was in turmoil.
