When Lin Wei, vice chairman of the Municipal Art Foundation, mysteriously fell from a building during a heavy rainstorm, forensic doctor Lin Mo intervened in the investigation with extraordinary calmness. A flickering 3D printed resin chip at the scene formed a strange echo with the "money laundering threat letter from the art circle" he secretly provided. As the investigation deepened, the truth was gradually revealed in the battlefield diary of Lin Mo's brother, sculptor Chen Zhe: the "Beware of the Sculptor" note left by his lover A Ye and Lin Wei recorded in the diary, as well as Lin Mo's forged money laundering evidence chain, began to collapse in front of the resin composition identification report (matching degree 99.8%).
This "accident" planned with sophisticated technology was actually a fatal lie spun by Lin Mo out of jealousy. He used 3D printing technology to forge cultural relics, tamper with evidence, and even implant resin chips in the fingernails of the deceased in an attempt to blame the crime on money laundering syndicates in the art world. However, the sudden appearance of A Ye, the "fatal flaw" file recovered in Lin Wei's computer (recording evidence of Lin Mo's crime), and Chen Zhe's collapse between trauma and truth, made Lin Mo's carefully designed parabolic trajectory (the resin block falling from the twentieth floor) ultimately point to himself - the forensic doctor who used a professional scalpel to cut open the sin, but was backlashed by paranoid emotions. When the "testimony" of resin penetrates the lies, this puzzle that is mixed with battlefield past, same-sex emotions and technological crimes finally exposes the most twisted cracks in human nature in the silent confrontation.
