Call the Midwife follows the nuns and nurses of Nonnatus House convent as they provide the expectant mothers of Poplar with the best possible care. Series 8 continues to explore complex medical and personal situations on the midwifery and district nursing rounds. It is now 1964 and it's evident how the times are changing: from the beacon of the contraceptive pill and the shadow of the 1967 Abortion Act, to the introduction of a new cancer-screening program. The nuns and nurses continue to face a variety of challenging issues including interracial adoption, cleft palate, sickle cell and cot death. And for one of the team, romance could be on the horizon.
