In Jiangcheng in 2026, Lin Hao, a senior student at Shihua Middle School, disappeared mysteriously on the night of the final exam. The next day, he was found in a closed storage room on the top floor of the teaching building. His body was precision cut, and the doors and windows of the storage room were locked, forming a perfect secret room. Chen Mo, a former criminal investigation backbone, was entrusted to intervene in the investigation. As clues were uncovered layer by layer, Lin Hao's unsent text messages, strange cutting patterns, and a falling case that was characterized as suicide three years ago gradually intertwined into a secret web. When the monitoring loopholes of the smart campus, the coerced art students, and the art teachers hiding secrets came to light one by one, Chen Mo relied on rigorous reasoning to crack the secret room conspiracy, uncovering the smuggling truth and old grudges behind the cut, and bringing two murder cases that spanned three years to light.
