In 1948, Chongqing was undercurrent. White terror shrouded the Kuomintang-controlled areas, and the underground party was walking on the edge of a knife. The mist-filled alleys, teahouses, newspaper offices, and military and political halls of the mountain city have all become battlefields. The "Tinder" organization of our party's Special Branch lurks in the heart of the enemy, using radio stations, secret accounts, and instigating rebellion as its blades to tear open the darkness. Agent Chen Yan, female telegraph operator Shen Qinghe, and the youngest traffic officer who was a patrol officer, the three of them are like nails piercing the enemy's heart. The forces of military commanders, central commanders, local warlords, and Pao Ge competed with each other, and intelligence warfare, psychological warfare, and life-and-death situations took turns taking place. A secret message, an assassination, and an instigation of rebellion all affect the situation of the country. Faith is like fire, burning in the darkest moments. This is not a legend fought alone, but a bloody epic written by a group of nameless people with their lives. Bullets will go astray, and people's hearts are unpredictable, but the direction remains the same: the dawn will come.
