Su Jin, a 24-year-old genius female forensic doctor, became the only survivor in the "Blood Wedding" case that shocked the country. However, she fell into a vegetative state for three years due to post-traumatic stress disorder and brain damage. After waking up, she lost the key memory of the case, was left with an uncontrollable slight tremor in her left hand, and her career was on the verge of collapse. Gu Huaiyuan, the 27-year-old captain of the Jiangcheng Criminal Police Detachment, was the main person in charge of the case that year and the "ex-boyfriend" of Su Jin's childhood sweetheart. In the past three years, he has been burdened with the double shackles of failing to solve the case and losing Su Jin, and has become cold and silent. Su Jin's awakening, like a pebble thrown into stagnant water, not only restarted the silent case file, but also stirred up the undercurrent hidden under the bustling river city. They must search for the truth in the fog, struggling repeatedly between trust and suspicion, and what is more terrifying than the murderer is the shadow under the backlight deep in the heart.
