Poplar welcomes a brand new cervical cancer-screening clinic to the Institute and Dr Turner (Stephen McGann), Shelagh (Laura Main) and Trixie (Helen George) are pleased to be part of the exciting new venture. One of their first patients is a young woman who is due to be married, but has never had a period. She has to be referred to St Cuthbert’s where she receives a diagnosis of a rare condition known then as Testicular Feminisation Syndrome. Trixie does her utmost to be supportive but the truth of the condition has larger repercussions than anyone could ever have imagined. The prospect of a new romance for Lucille (Leonie Elliott) brightens the mood at Nonnatus House and the husband of an expectant mother suffers with some inexplicable pains, similar to his wife’s pregnancy symptoms. Sister Frances (Ella Bruccoleri) faces her very real fear of public speaking when she is tasked with running her first Mothercraft session.
