The synopsis for the Christmas episode reads: “The midwives move the maternity clinic into new premises and are delighted when one of their first patients through the door is Rhoda Mullucks who the team know well.
“Rhoda is heavily pregnant, and understandably nervous, after her last baby was born with limbs that have been affected by thalidomide.
“Nurse Crane (Linda Bassett) cares for a heavily pregnant single mother, recently released from prison, while Sister Frances (Ella Bruccoleri) is called out to deliver a Sylheti mother’s child in a garment factory in a rough area of Poplar.
“Elsewhere, Fred (Cliff Parisi) decides that Poplar needs to come together to raise money for those families still affected by the train crash and pitches the wonderful idea of a festive talent show – Poplartunity Knocks!”
The Call the Midwife Christmas Special airs on Christmas Day at 7.55pm on BBC One.
