After seven consecutive spoofs of other movies, the Carry On crew returned to the world of work for this lively comedy that virtually takes up from where Carry On Nurse left off. The timing of another hospital picture couldn't have been better for Sid James, who was genuinely bedridden for much of the production. Consequently, most of the workload falls upon Kenneth Williams as a sneering consultant, Jim Dale as the clumsy Dr Kilmore, and Frankie Howerd, who makes an impressive series debut as a fussy faith healer. However, Charles Hawtrey steals the show, experiencing the pangs of a sympathetic pregnancy.

Francis Bigger, a notorious charlatan who tours the country lecturing on the subject of mind over matter, slips off the platform in the middle of his performance and ends up in hospital under the care of Dr Tinkle. The hospital is about to enter a period of total chaos.
