Based on the bestselling memoirs by Jennifer Worth, Call the Midwife follows Jenny Lee, a young nurse working as a midwife in London's East End, providing the poorest women with the best possible care. This series continues to follow Jenny and the other midwives as they deal with the all the problems Poplar has to throw at them. A very old and dirty woman dressed in rags is fascinated by the newborns, much to the disgust and fear of the mothers. But is there more to this woman that anyone realises? When a baby is abandoned at Nonnatus House at Christmas, the nuns wonder who would be desperate enough to do such a thing. And word soon spreads that Dr Turner is trialing the latest pain killer - gas and air. It's not long before all the women want a taste of it. A fascinating portrayal of birth, life, death and a community on the brink of huge social change, Call the Midwife offers a gripping insight into a world that is so drastically different from how we live now.
