In 1890, estranged brothers Tommy and Billy McBride are living far apart in Queensland, each dealing with the trauma that destroyed their family in different ways. Now 21, Billy bottles his guilt and justifies his past crimes while attempting to revive his father's former cattle run and navigate his feelings for the young widow Katherine Sullivan. Katherine, meanwhile, cherishes her newfound independence but is struggling to establish herself as head of the vast Broken Ridge cattle empire her corrupt late husband mercilessly built. But even in the outback, the past cannot stay buried forever. When a judicial inquest is ordered into the McBride family murders and the subsequent reprisal slaughter of the Kurrong people, both Billy and Police Inspector Edmund Noone -- the man who led the massacre -- are called to testify. The inquest forces Billy to relive events he has long refused to face. He desperately needs to find his brother, Tommy, who for years has been surviving in the wilderness, attempting to move on with his life. But Billy is not the only one looking for Tommy. Now the ruthless Noone is determined to find the young man as well, and silence both brothers for good.
