<P> Along with the next film in the series (Carry On Abroad), it features the highest number of the regular Carry On team . The only regular members missing are Jim Dale and Peter Butterworth . Dale would return belatedly for Carry On Columbus in 1992 and Butterworth returned in a major role in Abroad the following year . Butterworth was due to play Freddy but was unable because of other work engagements . </P> <P> Sid Carter (Sid James) is the cunning head of a criminal gang that includes the longhaired drip Ernie Bragg (Bernard Bresslaw), the cheeky Freddy (Bill Maynard) and Sid's honest son, Cyril (Kenneth Cope). Cyril does not want a life of crime, but is emotionally blackmailed by his father into going along with his scheme to rob Finisham Maternity Hospital for its stock of contraceptive pills and sell them abroad . Cyril reluctantly disguises himself as a new female nurse to case the hospital and the booty . Assumed to be one of the new student nurses who have just arrived, he is assigned to share a room with the shapely blonde nurse, Susan Ball (Barbara Windsor). Unfortunately for Cyril, he also catches the eye of the hospital lothario, Dr Prodd (Terry Scott). </P> <P> Sir Bernard Cutting (Kenneth Williams), the hypochondriac registrar of the hospital, is convinced he's undergoing a sex change . When he consults the nutty Dr F.A. Goode (Charles Hawtrey), Goode dishes out psychiatric mumbo jumbo, stating that Cutting merely wants to prove his manhood, and Cutting decides he is in love with Matron (Hattie Jacques). Matron, on the other hand, has more than enough to contend with on the wards, with the gluttonous patient Mrs Tidey (Joan Sims) who seems more interested in eating than producing a baby, and her long - suffering British Rail worker husband (Kenneth Connor) who continually hangs around the waiting room . </P> <P> When Cyril goes back to Prodd's room to get a map of the hospital, Prodd attempts to get intimate, only to be knocked across the room . Prodd and Cyril are called out on an emergency when lovely film star Jane Darling (Valerie Leon) goes into labour, but as Cyril knocks Prodd out in the ambulance, he is forced to deal with the actress's triplets being born . Jane Darling is delighted with Cyril and hails "the nurse" a heroine for her efforts, bringing fame to the hospital . Susan uncovers Cyril's disguise, but as she is in love with him, does not reveal the truth . </P>
