Sour Annie Tatum, an experienced female prospector, agrees to help Kelly, Flip and their men capture wild horses in exchange for a free ride into town. Annie is thrown from her horse during the roundup and badly, if not mortally injured. Flip and Harlan, one of the wranglers, agree to stay with the old sourdough until she dies, but the wrangler, knocks Flip unconscious, steals Annie's gold, guns, and horses, leaving the young stagecoach driver and old prospector alone and defenseless in the desert.
