Cameron Black figured he was due for some luck. With a posse on his trail and the desert crawling with hostile Indians he finally managed to make it to the isolated army outpost. The trouble was the post was manned only by a skeleton crew of weary soldiers, among them three would-be deserters waiting for a chance to steal the army payroll.Also trapped inside by circumstances were a US marshal Black had known on the back trail, his young prisoner and a group of female camp-followers. Among them was Cameron's old-time lover.Even with the Comanches gearing up to attack the outpost, Cameron felt like making a dash across the desert, because there was nothing here but certain trouble.
