In 1939, at the brink of WWII, an English aristocrat, Lady Sarah Ashley, travels to the northern Australian Outback to confront her husband, who she suspects of infidelity, and to coerce him into selling their failing cattle station, Faraway Downs. Upon arrival, she finds that her husband has been murdered, and the future of the property is in jeopardy. Sarah reluctantly partners with a rugged local stock-man named Drover, who helps her in her quest to save the cattle station. They embark on a daunting drive across hundreds of miles of harsh desert to Darwin, facing challenges from the unforgiving landscape, a conniving cattle baron trying to monopolize the industry, and deep-seated racism against the indigenous population.

Caught up in the societal changes and unrest of pre-war Australia, Sarah forms an unexpected bond with a mixed-race Aboriginal child, Nullah, who reveals a secret about Faraway Downs that can alter its destiny. Together, Sarah, Drover, and Nullah work to protect the cattle station from being taken over by the cattle baron, who will stop at nothing to dominate the beef market. The trio's emotional journey is laced with adventures and discoveries that force them to confront their personal demons and societal prejudices, against the backdrop of the impending global conflict and the breathtaking beauty of the Australian wilderness.
