Freelance surgeon Dr. Daimon Michiko struts into a University hospital, is mistaken by the administrator for a sleazy Roppongi bar hostess, and takes on the most difficult case. Displaying an independent air gained from hard won experience in third world clinics and hospitals, Dr. Daimon refuses to do anything that doesn't require a doctor's license, from secretarial duty to golf games and leaves work promptly at 5 p.m. As she blows past the institution's cliques and hierarchy, the staff becomes infuriated as patients are cured one after the other. Her representative, Dr. Jonouchi Hiromi, who may be the real (failed)"Doctor X," submits an exorbitant bill and a melon to the institution, which usually leads to a senior staff shakeup. In between surgeries, Dr. Daimon rests at Dr. Jonouchi's physician's exchange, losing game after game of Mah Jong.
