The journalist Ted York (Terence Longdon) is rushed to Haven Hospital with appendicitis. The ambulance gets there at top speed, but only because the driver wants to know the result of a horse race. Ted is given a bed and is instantly smitten with Nurse Denton (Shirley Eaton). The other nurses are incessantly having to respond to the calls of the Colonel (Wilfrid Hyde-White), who has a private room. He is an inveterate gambler and is having his bets placed by Mick (Harry Locke), the orderly.
