This unnamed hospital was located at a Los Angeles university campus. Dr Lochner was the chief of personnel, a really good doctor, and a compassionate person. His right-hand assistant was Dr Joe Gannon, a young surgeon and trusty pal of Lochner's. By the second season, Dr Gannon was promoted to Director of the Intern Service, a job suited for a professional able to relate with interns. Around these two medics, there were several doctors and nurses who worked alongside and specially Miss Wilcox, the efficient secretary.
