Synopsis The Arizona wilderness, 1880. Gen. Fletcher Blackwell sends a message telling Capt. Walsh, who is escorting a wagon-train through Apache territory, heading for the fort at Furnace Creek, that he should cancel the escort and rush to another town. Apache leader "Little Dog" is leading the attack on the wagon-train and massacring everyone at the poorly manned fort. As a result the treaty is broken with the Indians, and the white settlers take over the territory, with the help of the calvary, as the Apaches are wiped out, and only "Little Dog" remains at large. Gen. Fletcher Blackwell is court-martial-led for treason. The General's 2 sons, Cash Blackwell and Capt. Rufe Blackwell, each with a different disposition, go about trying to find evidence to clear their father's name.
