Zhou Ci's father, Zhou Zhengyuan, was once a well-known independent consultant in the criminal investigation industry. He was known as the "human polygraph" for solving many unsolved cases. However, eight years ago, Zhou Zhengyuan was accused of accepting bribes and fabricating evidence while investigating the disappearance of a wealthy businessman. He was eventually imprisoned unjustly, and all his family property was seized. The Zhou family collapsed overnight. His father died of depression in prison, and Zhou Ci was forced to drop out of school and live in the market.
Now, Zhou Ci returns to the old house left by his father - an old house that is about to be demolished. Next door lives his neighbor Wang Fugui, who appears to be enthusiastic but is actually greedy. He has been coveting the Zhou family's land for many years and has secretly colluded with the demolition office. Zhou Ci endured the humiliation, working in a scrapyard during the day, and studying the incomplete notes left by his father alone at night. He possesses a special ability - "touch trace recall". Whenever he comes into contact with items related to unsolved cases, fragmented images of key scenes can briefly appear in his mind.
When workers disappeared one after another in the building materials factory owned by Wang Fugui, and all evidence pointed to Zhou Ci, a battle of wits quietly began. Zhou Ci must use reasoning and golden fingers to restore the truth step by step in the cracks between the police, unscrupulous businessmen and greedy neighbors, clear his father's grievances, and get himself out of the quagmire.
