Set in rural Australia in the years following World War II, this beautifully acted, sharply written series follows the fortunes of a woman returning home after spending two decades abroad.

In the final season, Sarah Nordmann finally marries wealthy landowner George Bligh. But as Sarah takes her place as lady of Ash Park, George's mother, Elizabeth, feels pushed out of the household. George's son, James, returns from abroad to start a business, while his daughter, Anna, lives in Hawaii with her sister-in-law, hiding a secret from the family. The Bligh's face tragedies, betrayals, and new beginnings that will challenge their relationships...

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.

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.

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.

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.

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.

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.
