Ryutaro Asada is enjoying his peaceful life in the countryside, when he is visited by Akira Kato, assistant professor of the Faculty of Cardiac Surgery at Meishin University Medical Hospital.
Ryutaro is a genius surgeon who used to lead "Team Medical Dragon," a world-class NGO medical team. In harsh environments that lacked medicine and electricity, Ryutaro witnessed many lives pass away. At the same time, he saved many other lives, helping his matchless skill overwhelm other doctors.
As a female doctor, Akira managed to become an assistant professor. She has ambitions to be promoted to professor by succeeding in a surgery using the Batista technique — an extremely difficult type of heart surgery — and also by writing a paper on it. A year ago, Akira witnessed Ryutaro's skills when he was an NGO doctor. That's why she recruits him and asks him to use the Batista technique. Since Ryutaro's arrival, urgent patients who would have been abandoned in the past, are miraculously saved by the "hands of God."
