At Chun City Law School, summer is a battle between cicadas and legal statutes in the stifling heat. Top student Cui Xinqi's life revolves around a revision schedule precise to the second, until one stormy night, after getting drunk, he is found by Zhao Jiayu, a bar server and saxophonist whose youth has been scarred by predatory student loans. When forged medical records uncover a buried feud between father and son, and the call of grassland throat singing shatters the glass walls of the courtroom, two men whose lives have been assigned a price find themselves making music together in the 98 days before the bar exam, using the law as their bow and medical records as their score, playing in the gaps between lies and truth.
On the back of that summer's mediation agreement, a Mongolian love poem and Article 1017 of the Civil Code blur into mottled blue in the rain. Ten years later, a time capsule buried beneath a boundary marker is beginning to sprout. The confessions whose frequencies were filtered out by tinnitus will finally find an echo of long-awaited justice on a night when years of frost have gathered.
