In this city built of steel, concrete, neon lights and countless lies, the truth is a scarce luxury.
Shen Zui, a person who can "see" lies. To him, every acceleration of his heart, every contraction of his pupils, and every involuntary tremor of his muscles were all the ugly echoes left by a lie in the air. This talent, or curse, made him the secret weapon of the Municipal Public Security Bureau, and also made him an island isolated from the world.
He is cynical, speaks harshly, and uses his laziness and poisonous tongue to wrap a heart that has been burned by the truth. Until a "perfect secret room" murder case occurs, the deceased is a hot technology upstart in the city, and all the evidence points to a suspect with a perfect alibi.
When the police were helpless, Shen Zuan was "invited" out of his apartment, which had not seen the light of day all year round. He thought this was just a well-paid intellectual game, but he never thought that every clue in this case was like a thread of fate, dragging him back to the nightmare five years ago that made him lose everything...
This time, when lies are nested layer by layer and murderous intentions are approaching step by step, can his eyes, which can see through illusions, capture the only real answer in the endless shadows?
