Sydney, July 1850. Victim of a sordid plot, young Judith Lavallière is exiled to Australia on false charges. Sentenced to domestic service under the thumb of an alcoholic English colonel, she flees and finds refuge, beyond the known lands, in the mysterious outback Australian. Taken in by Aborigines, she will discover a strange and endearing people, learning to survive in a hostile, limitless, but fascinating desert. Her destiny will nevertheless bring her back to civilization, in the Melbourne region, at the time of the gold rush, in which she participates. Willful and tenacious, Judith makes her fortune, then stands up against the governor who exercises an odious tyranny over the gold seekers. But is this fight against an all-powerful and unscrupulous adversary not lost from the start? Especially when the ghosts of a troubled past that she would have preferred to forget arise before them.
