This second film in the Carry On series overdoses on bedpan, large needle and inedible food gags, but, as most of them are funny, no one will mind in the slightest. Hattie Jacques is superb as the bullying matron whose clipped supervision of nurses Shirley Eaton and Joan Sims prompts Kenneth Connor, Leslie Phillips and Kenneth Williams to give her a taste of her own medicine, while Wilfrid Hyde White has fun as a lecherous colonel in a private ward. It's loosely based on a forgotten play called Ring for Catty.

In Haven Hospital, a certain men's ward is causing more havoc than the whole hospital altogether. The formidable Matron's debut gives everyone a chill every time she walks past, with only Reckitt standing up to her. There's a colonel who's a constant nuisance, a bumbling nurse, a romance between Ted York and Nurse Denton, and Bell wants his bunion removed straight away, so after a couple of pints, the men decide to remove the bunion themselves!
