Genius surgeon Gu Yan met the strange survivor Lin Wan after a failed operation late at night. Faced with the death of her family, Lin Wan's calmness made Gu Yan suspicious, and he accidentally got a glimpse of the secret that she might be the murderer behind the scenes. He didn't say anything, but he was involved in the whirlpool of her fate.
During the investigation, Gu Yan discovered that Lin Wan was actually a college student from a prestigious university. After further understanding, he learned the truth about the long-term inhuman abuse she suffered as an adopted daughter. Beneath the surface of obedience is a revenge that she has carefully planned for many years. Gu Yan felt sorry for her plight and was determined to become her accomplice and sharp edge, but was repeatedly rejected: "You are in the light and should not accompany me to death."
However, when Lin Wan's final plan was launched and she wanted to die with her enemy, Gu Yan arrived in time with key evidence - he found out the old case of her adoptive father's murder of her biological parents. Ultimately, sin is judged by the law. Lin Wan chose to surrender for the past, while Gu Yan was waiting for her new life in the light. The two worlds collided, eventually redeemed each other, and headed towards the dawn together.
