Things aren’t all merry and bright at Nonnatus House this Christmas. The halls aren’t decked and Sister Monica Joan looks like she’s in trouble.
The first full trailer for this year’s BBC1 festive special sees the elderly nun disheveled and wandering alone in a forest while snowflakes swirl around her.
Back in the East End, Sister Julienne is calling the authorities, and the midwives looked troubled rather than cheery.
At least someone’s providing some seasonal goodwill. Fred’s donned his Santa suit for Father Christmas’s annual trip to Poplar, while Shelagh promises to put on a show to be proud of as cameras start rolling in the local church.
Call the Midwife returns for a Christmas special on Christmas Day at 7:30pm on BBC1
