Call the Midwife

This year, Christmas takes the Nonnatus team a very long way from Poplar. Senior members of the order travel to Hong Kong to deal with a crisis at the branch house, while back home Dr Turner and Shelagh search for May's birth mother. As ever it mixes big-hearted storytelling with the odd heartbreaking moment, so keep the tissues within reach of the good chair. It's the first of two Christmas specials, with the second following on Boxing Day, which makes it a proper two-night treat. Kind, warm and gently moving, it's become a Christmas Day habit for plenty of households, and rightly so.
