Aoi Misora is a third-year nurse at a prestigious hospital. After she is involved in trouble at the Emergency Center, she is transferred to a medical ward of an affiliated hospital. Unlike her previous workplace, the medical ward is a crucial place where patients who survived the emergency room must be looked after with extreme care. But it's also a place for dishonest and unskilled doctors. Moreover, it is also a place for cozy ties between politicians and doctors, where the priority is not patient care but profit.

Still, Aoi puts every effort forward to take care of patients with her heart and soul. The harder she tries, the more she is alienated from the proud doctors. But with the support of another nurse, Kyoko Komine, and also Dr. Takagi, Aoi succeeds in changing the minds of those around her.
