Lu Chuan can hear a couple whispering three hundred meters away, yet he always ruins his instant noodles. On his first night as an emergency hotline operator, he hears a drunk caller rambling about a “possessed toilet” and recognizes the choking sobs of a woman being strangled with a chain. From then on, his “golden ears” become the bane of criminals: he detects domestic abuse by listening, busts casinos by hearing the dice, and can even discern the deepest fears in people’s hearts.
He teams up with Zhao Yan, a policewoman who is afraid of the dark and cockroaches but has astonishing fighting skills. One is a bickering partner who “hears” the truth; the other “reconstructs” crime scenes with her eyes. From laughable cases that turn into one absurd joke after another, the pair go on to confront loan sharks and an illegal lending racket, then get dragged into a deadly sound-wave game devised by a deaf genius known as the “Sound Mentor.”
When a recording of a plea for help from the Republican era plays in the dead of night, and echoes from a childhood fire once again sear his eardrums, Lu Chuan realizes that he is protecting more than the peace of this city. He is part of a redemption through sound that spans time.
The night shift never ends, and he listens closely to every silent cry for help.
