"Call the Midwife" is a drama series based on the memoirs of Jennifer Worth, offering an insight into the world of midwifery and family life in 1950s east London. The community is seen through the eyes of newly qualified nurse Jenny Lee (Jessica Raine) who arrives at Nonnatus House to live and work as a midwife alongside an Order of Nuns. She is supported by Sisters Julienne (Jenny Agutter), Evangelina (Pam Ferris), Bernadette (Laura Main) and Monica Joan (Judy Parfitt); nursing colleagues Trixie (Helen George) and Cynthia (Bryony Hannah); and handyman Fred (Cliff Parisi). In the first episode, Jenny is allowed to handle her first case alone - the care of a woman during her 25th pregnancy. Miranda Hart joins the cast in episode two as clumsy new midwife Chummy Browne. Vanessa Redgrave provides narration as the voice of older Jenny. The series quickly resonated with viewers, attracting around 10 million viewers, and a second series was commissioned shortly after the second episode aired. It premiered on BBC One in January 2012.
