Raised in a family where her father is a general practitioner, Miyama Shizuku (Naka Riisa) initially aspired to be a doctor to please her father, but he was against it. Vowing to become a doctor no matter what it takes, Shizuku entered the faculty of medicine on a scholarship without any financial assistance from her parents. She is now a first-year houseman at a university hospital’s accident and emergency centre for a three-month training along with Yazawa Kei (Hayashi Kento), Manaka Junichi (Masuda Takahisa), Koiwai Hinako (Omasa Aya), Arashiro Sachi (Ishibashi Anna). Half a year into becoming doctors, they still do not have the ability to save people. Unable to do anything, they can only stand dazedly rooted to the spot in the emergency centre where every minute counts. They encounter patients with anorexia, bulimia, suicidal tendencies, depression … … While some people refuse social security and push their children to the brink of starvation, others take advantage of the state subsidies for medical treatment to go to the hospital in an ambulance instead of a taxi. In addition, the reality of the medical scene is overworked doctors because of their severe shortage. The five of them do not have high aspirations as doctors and also do not know which department they should move on to. To begin with, they do not even know if they truly want to be doctors. Trained by their experienced seniors and a variety of patients, they develop the qualities of a doctor and mature as adults.
