The highest-rated drama in BBC history returns to PBS Presents in March 2013 Â Less than a year after the first season finale, PBSâ€™s hit series Call the Midwife returns to Sunday nights this spring with an all-new eight-episode season. Fans of Downton Abbey and Mad Men have fallen in love with this candid look at post-war London. In the 1950s, twenty-two-year-old Jenny Lee leaves her comfortable home to move into a convent and become a midwife in London's East End slums. While delivering babies all over the city, Jenny encounters a colorful cast of womenÂ—from the plucky, warm-hearted nuns with whom she lives, to the woman with twenty-four children who can't speak English, to the prostitutes of the city's seedier side. Â Â Â Â Â Â Â Â Â Â Â Based on Jennifer Worth's bestselling memoirs, Call the Midwife will continue to delight its millions of viewers in the U.S.
