Emergency! (1972)

S5E2 The Old Engine Cram

John and Roy might be on the verge of selling their vintage fire engine. The crew responds to a series of emergencies: a motorcyclist with a back injury, a man who suddenly collapses in the station, and another who has tumbled off a cliff. Additionally, they face a crisis within their ranks when a training exercise goes awry, resulting in a trainee getting splashed with dangerous chemicals.
