A medical accident caused the genius doctor Lu Zhengyang to lose his license and memory, and he ended up running a rogue clinic in a village in the city. Three years later, he was invited to the emergency department of a city hospital to save lives, but found that he could 'see' the lesions in the patient's body - at the cost of forgetting a piece of the past every time he used it. Qin Moran, the director of the emergency department, recognized this 'charlatan' at a glance as the colleague she reported to him back then. The two went head-to-head in the emergency room, but were forced to work together to deal with a bizarre poisoning case.
