Under the neon lights of the southern coastal city of Qingzhou, there are secrets of the alternation of old and new. Lin Xi, a 22-year-old forensic doctor, joined the job with the suspicion that his mother had "accidentally drowned" and was determined to use a scalpel to uncover the truth. A note written "Red Star Chemical Plant, 3:15" and an unfinished clock pattern among her mother's belongings became her only clues to the answer. The scalpel cuts open not only the body, but also the sins buried by time. In the final confrontation in the ruins of the factory, Lin Xi must use professionalism and courage to turn the stopped clock again and let the silent corpse tell the truth that was ten years late. And this journey of chasing the murderer has long been destined to be her journey of growth and transformation.
