1920's Mexico and the American Southwest hold many dangers, as the last Apache strongholds persist against the foreign invaders. Hard as nails, Confederate serviceman Jock MacNeil receives an unexpected invitation to guide runaways from a reservation to a stronghold in Sierra Madre. Facing both Mexican and American authorities, and the Apache Wars raging around them, Jock witnesses first-hand the terrors of war, and his own transformation from a man of faith to Apache spirituality.
