At the Long Hampton Hospital, Dr Jimmy Nookey seems to attract trouble, beginning with an incident where he enters the women's washroom by mistake, frightening the highly-strung Miss Armitage out of her senses.

During some misadventures with the X-ray machine, Nookey triggers a massive short circuit in the hospital's electrical system, resulting in more mayhem.

With the sympathetic Matron and his moody boss Dr. Frederick Carver now watching his every move, Dr. Nookey drinks, at a staff party, a fruit punch spiked by jealous Dr. Stoppidge.

Gladstone quickly discovers that Nookey is making a fortune from his serum, and cuts off his supply to deliver the product in person and get in on the action.

Eric Rogers arranges the theme from Steptoe and Son when Wilfrid Brambell appears, as he did with Harry H. Corbett in Carry On Screaming.
