As the sweeping Australian saga returns, four years have passed and nurse Sarah Nordmann (Marta Dusseldorp, Janet King) and her son are safe and happy, despite having to live separately from wealthy patriarch George Bligh (Brett Climo, Snowy River: The McGregor Saga) for political reasons. George's formidable mother, Elizabeth (Noni Hazlehurst, Little Fish), has finally found love and happiness with her new husband, while her granddaughter, Anna (Abby Earl, The Great Mint Swindle), makes waves as a single socialite. But the Blighs' contentment is threatened when George's murderous wife, Regina (Jenni Baird, The 4400), petitions for release from the insane asylum. Set in 1958, this "captivatingly filmed, deeply romantic drama" (The Wall Street Journal) continues to address thorny social issues with intelligence and aplomb. The phenomenal cast also includes Craig Hall (The Doctor Blake Mysteries), Sara Wiseman (Mercy Peak), Frankie J. Holden (Something in the Air), Matt Day (Rake [Australia]), Aaron Pedersen (Jack Irish), and Arianwen Parkes-Lockwood (Underbelly).
On Anzac Day, Henry, now head of surgery at Inverness Hospital, spars with Sarah and Jack over the treatment of Frank, an Aboriginal veteran. Regina claims to have made a breakthrough in her treatment and reaches out to George from the asylum.
While Sarah attempts to track down a local Jewish girl who ran away from her uncle, Sarah and George argue about what religion in which to bring up their son, David. Douglas ignores orders to rest after his health scare.
To Sarah and the Blighs' horror, Regina is released from the asylum. George ruffles feathers as he considers converting to Judaism, while Elizabeth finds it difficult to participate in Sarah's Jewish traditions.
Having severed ties with Sir Richard, Regina returns to her cottage. There, Sarah confronts her and urges Regina to leave Inverness. After an indiscretion at Ash Park, the Blighs find out about Anna's relationship with her publisher, Ed.
George takes Sarah and David with him to Canberra, despite the damage it could do to his political career by bringing his mistress and illegitimate son into the public eye. Elizabeth and Jack decide not to tell Douglas about his deteriorating condition over Henry's objections.
Sarah panics when she thinks she sees a villain from her past in Canberra. Douglas finally knows the truth about his illness and asks Jack for help. Anna contacts Richard for advice about getting out of a publishing contract with Ed.
The Blighs contend with Douglas's death and planning his funeral, but Elizabeth takes it especially hard and lashes out at the rest of the family. Regina urges George to examine their accounts, suspecting that Richard will attack him financially, but Sarah can't bring herself to trust Regina.
Feeling distant from the rest of the family, George considers selling the farm. As Inverness prepares for the annual open day and fete in support of the hospital, Richard schemes new ways to bring down the Blighs.
Douglas's estranged son, Matthew, visits Elizabeth, who only recently learned of his existence. Sarah remains cautious as George works with Regina to devise a plan to distract Richard-but they need Jack to cooperate.
Jack begins his political campaign running as an independent, while George comes clean to his constituents about Sarah and David. As Matthew grows closer to Olivia, Anna worries that she'll never find love again and turns to alcohol to dull her pain.
