The only daughter of the city's richest man has been kidnapped. The kidnappers demanded a sky-high ransom and threatened to "call the police and have their lives broken." The police were helpless.
After private detective Bei Zhiye took over the case, he did not trace the kidnapper's phone number - he stared at the anxious face of the richest man and drew a question mark in his mind:
"Why is your anxiety only 7 points?"
This question brought up a monstrous three-level game. From kidnapping cases to serial disappearances, from philanthropists to secret room frame-ups, every time Baizhiye thought he saw the whole picture, there would be new pieces that shattered the entire puzzle in his mind.
"The truth is not found," he said, "it is pushed out by one mistake after another."
But what he doesn't know is: this time, he himself is someone else's "mistake".
