Petrichor - Rust in the Rain Volume 1 (หยดฝนกลิ่นสนิม English version)

The first field deployment of Lieutenant Tul, a rookie female officer assigned to the Criminal Investigation Department, unexpectedly brings her face-to-face with Dr. Cherran, a female physician from the Institute of Forensic Sciences. Their differing work attitudes create a considerable gap between them, making it challenging for both to find common ground.

Amidst the crime scenes reflecting societal issues, Detective Tul also contends with pressures from a working system favoring influential groups within the country. She navigates through the interference aimed at protecting allies and the societal currents that could significantly influence the case's outcome.

At least Tul's integrity remains intact amidst these challenges. When she teams up with Cherran, A female forensic doctor, they methodically analyze the evidence left at crime scenes, leading them closer to identifying the perpetrators in each case. With time, both Tul and Cherran grow to trust each other more, working tirelessly to protect the lives of the innocent and ultimately deliver justice to the families of the victims.
