Chen Xiaozhou, an ordinary young man who delivers food, accidentally touches a mysterious electrical box on a rainy night, and suddenly he can hear everyone's voices - the hypocrisy of his boss, the indifference of customers, the jealousy of passers-by, and even the pet dog's "want to eat meat bones." When he thought it was a curse, he unexpectedly heard the despair deep in Su Yuqing's heart: "If no one saves me, I will jump off the building tomorrow." In order to save her, he was involved in a wealthy conspiracy, and every voice he heard contained a fatal truth. When lies are heard and kindness becomes a weapon, he, a delivery boy, becomes the most dangerous "mind reader" in the city.
