Emergency! S03 E04 An English Visitor

"Squad 51, this is Rampart. Continue to monitor patient and transport immediately."

A paramedic from England has a stint with Station 51 observing Roy and John whose rescues include a structure fire, a wild-west performer, a car accident and a man trapped in heavy machinery. The visitor saves John's life. At the hospital Dr Brackett treats a rock singer in a diabetic coma and Dr. Early has problems with a defiant nurse.
