Dr Richard Hare is a recently graduated medical intern at St Swithins Hospital. When his new romantic interest, nurse Sally Nightingale, suddenly leaves the hospital, he is devastated. He also leaves after being offered a job in private practice. But when his senior partner, Dr Cardew, has to visit
California for a few months, Hare is left in charge. He is joined by Dr Tony Burke who proceeds to airily order expensive equipment that the practice cannot afford but leaves the practice after breaking an arm. Dr Nicola Barrington joins the practice and Hare is suddenly in love again. The romance doesn't go well, especially when Sally re-appears and takes the job of practice secretary and eventually Nicola leaves. Hare struggles through various comedic and other complications, mainly stemming from Burke's amorous attentions to female patients. After enlisting Sir Lancelot Spratt's assistance to save a young dying boy, he diagnoses Spratt with
appendicitis and decides to operate, despite Spratt's loud objections. He objects even more when Dr Burke fills in at the last moment as the
anaesthetist. Despite Spratt's vociferous protestations, the operation is a success. Hare is reunited with Nicola and returns to St Swithins. ==Main cast==
