Dave Harmon had a mission--take a woman & the guns the army desperately needed across the burning malpals to Fort Whippie. But the desert was Apache territory. And Harmon's small wagon train was easy prey for marauding outlaws. Faced w/ scorching sand & killing thirst, Dave found trechery within his own wagon train. He had to destory everyone who stood against him or lose the guns, the woman & his life.
