The first two series and the 2012 Christmas special of the BBC drama adapted from Jennifer Worth's memoirs about a group of midwives working in East London in the 1950s. Jenny Lee (Jessica Raine) gets her first job at Nonnatus House which she soon realises is a nursing convent and not a hospital, as she had assumed. As she begins caring for patients, she gradually becomes accustomed to her new environment, making friends with fellow midwives Cynthia (Bryony Hannah), Trixie (Helen George) and the clumsy Chummy (Miranda Hart). In series two, it's 1958, and while Jenny has her hands full dealing with an abused patient, Trixie and Sister Evangelina (Pam Ferris) are forced to board a Swedish cargo ship to tend to the captain's pregnant daughter. In the Christmas special, the discovery of an abandoned baby on the convent's doorstep proves to be a catalyst as the community come together to try to trace the child's mother. Elsewhere, Jenny finds herself drawn into the mystery surrounding elderly local woman Mrs Jenkins (Sheila Reid), while Chummy is determined to stage an unforgettable nativity play.
