The multi-award-winning drama enters a new decade, the 1970s, which brings with it new challenges for Nonnatus House - and to British society. A new series of truthful and tender stories, as always rich in compassion and heroism. The Seventies start as they mean to go on, with Nonnatus House plunged into disarray when activists staging a bid for independence blockade access to the Isle of Dogs. Amid the poverty and uncertainty of life in a declining Docklands, the midwives must also face cases of manic depression, gonorrhoea, spina bifida, abortion – and an apparently immaculate conception.
