Emergency! (1972)

S3E4 An English Visitor

A paramedic from England spends time at Station 51, shadowing Roy and John as they respond to various emergencies, including a building fire, a wild-west entertainer, a vehicular crash, and a man caught in heavy machinery. During one of these incidents, the visitor ends up saving John's life. Meanwhile, at the hospital, Dr. Brackett is busy treating a rock star who has slipped into a diabetic coma, while Dr. Early faces challenges with a rebellious nurse.
