In Japan's Saitama Prefecture near Tokyo, a patient died after being turned away by a number of hospital Emergency Rooms. Other patients have similarly been put in jeopardy; and even for minor ailments, treatment is hard to get after hours or during holidays. In response, a pioneering doctor has established an after-hours clinic, assisted by equally dedicated nurses. Working in shifts through the night, they cope with wave after wave of walk-ins and ambulance admissions. Other medical practitioners help out part-time; but the clinic is caught between a sense of mission and some harsh limitations. We observe their grueling schedule during Japan's annual Spring holidays in May.
