It is 1846, and the hard-working Englishman Rudolph Birkett embarks for a new job in South America, unaware of what fate has in store for him. He leads a tranquil everyday life there, eagerly waiting to marry the virtuous Emma upon his return to England. But that is all over when, in Buenos Aires, he meets Gordon Hadley, a powerful British businessman who used to operate in the mountains. An astonishing discovery had led Hadley and his small army to the land ruled by the Aborigines. And only Rudolph Birkett, protected by US Major Boyd Mackenzie’s military team, can find a way out of what is happening there.
