A gang of thieves plan to make their fortune by stealing a shipment of contraceptive pills from Finisham maternity hospital. They assume disguises and infiltrate the hospital, but everything doesn't go according to plan. The hypochondriac consultant Sir Bernard Cutting, Matron and the doctors and nurses at Finisham have a habit of getting in the way.

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