In Shanghai on a rainy night, everyone wears a mask, and every relationship has hidden plots.
In this chess game where various forces are intertwined, Ruan You, Lu Xingzhou, and Feng Zheng, the three female directors of the Operations Department, the Intelligence Department, and the Secret Service Department, appear to be on the same side, but due to the safety of Shanghai, they have to put aside their personal grudges and cooperate cautiously.
When a key assassination mission of the Operations Division failed, Division Chief Ruan You was furious, and the entire department was shrouded in depression. As the Secret Service launched an internal investigation, Wen Yao, the backbone of the Operations Department, was involved in the whirlpool due to his relationship with the singer Xue Chuan, and Xue Chuan's true identity gradually emerged.
