Eleven years ago, Xia Qinmi lost her younger brother in Ninghai City, and her mother "committed suicide out of fear of crime." In desperation, Lin Shiyuan took her to flee to the winter market and signed an invisible marriage contract in exchange for ten years of asylum. When the contract expired, she returned to her hometown with the divorce agreement and became a professor of acoustics at the university and a special consultant in criminal investigation, using her ears to catch lies and truth. The first case pointed to the blond boss of Lan Yufang - Gu Yiwen. The young man who had been arrogant but protected her well has now become a suspect. The transient high-frequency tearing in the recording, the fake limp steps, the dusty confession on the tape... Everything points to the truth about his brother's death twelve years ago. Some are seeking revenge, some want to close the case, and some are hiding inside the police station. Xia Qinmi put on her headphones and peeled away the layers of noise, only to hear the heartbeat she had never dared to face.
Gu Yiwen said: "Eleven years ago, I never hated you. I only hated myself and didn't protect you."
And she finally stopped running away. In the forbidden words in the ears, the truth is like snow, covering everything, but there is always a voice, waiting to thaw.
Eleven years later, Xia Qinmi, who fled her hometown, re-entered this land as a voice criminology instructor invited by the police station.
