After a car accident on a rainy night, 34-year-old emergency specialist Su Wan returned to the night shift that changed her life when she was 22 years old.
In her previous life, she took the blame for her boss and ended up with her family ruined and her reputation ruined.
In this life, she sticks to the bottom line of her white coat, stops illegal operations, saves dying patients, exposes the shady industry, trains newcomers from a position that everyone can bully, and becomes the most dazzling light in the emergency room.
The lights in the emergency room are always bright, and she uses her medical skills to not only save patients on the verge of death, but also save herself who is about to live again.
