On a rainy night, Qin Feng took in Ling Shuang, a woman who had passed out at the door of the "Evening Breeze" cafe. He was once a "police database" who could see through lies with one look, but now he just wants to remain anonymous. But there's something wrong with this waiter - she has amazing fighting instincts and whispers at an encrypted frequency in her dreams. When the killer came to the door disguised as a maintenance worker, Qin Feng saw through it instantly; and behind the serial murders, he actually revealed the truth about the unsolved case that led to his retirement five years ago.
Ling Shuang is the number one defector from the secret service organization "Hive", and Qin Feng's past is also mired in conspiracy. From outsmarting the stand-in to attacking the stronghold at night, he broke the situation with his subtle expressions, and she defeated the enemy with her skills. When his partner's last words pointed to the mystery of "Evening Breeze", Qin Feng's golden finger awakened and turned on the hundred-second deduction mode. "It's our turn." - A secret battle about truth and redemption begins.
