It's the 1950s and Jenny is a new young midwife who's just started a job in East End London. Join her as she makes friends with her colleagues of nursing nuns and encounters the lives of the families she treats.
Sharon Horgan stars as Helen, a falsely imprisoned woman who remains blindly optimistic in the face of an uncaring outside world and an insane prison life. She is joined by Jennifer Saunders as a deranged, "sexual Margaret Thatcher" prison governor, Bryony Hannah as her arsonist cellmate, and Geoffrey McGivern as her useless lawyer.
