As the smash hit drama returns, Nurse Sarah Nordmann (Marta Dusseldorp, Jack Irish, Janet King) and the wealthy Bligh family face new challenges amid sweeping social change in 1950s Australia. Villainous Regina (Jenni Baird, The 4400) has finally ensnared Bligh patriarch and political aspirant George (Brett Climo, Snowy River: The McGregor Saga) in marriage, but she continues to plot against Sarah, exploiting the rising fear of Communism to target her rival. As Sarah teams up with formidable dowager Elizabeth (Noni Hazlehurst, Little Fish) to expose Regina, James (David Berry, Outlander) and his estranged wife, Olivia (Arianwen Parkes-Lockwood, Underbelly) forge a fragile peace, and Anna (Abby Earl, The Great Mint Swindle) strives to advance her literary career. The supremely talented cast also features Craig Hall (The Doctor Blake Mysteries), Frankie J. Holden (Something in the Air), Aldo Mignone (Danger 5), and Sara Wiseman (Mercy Peak).
