Man from the sky: Paul Torridon and his plainsman guide ride together on their way to Fort Kendry. But one morning the guide has vanished without a trace, and Paul is left with just his faithful steed. Paul knows that his destination will be near impossible to find without a guide, and that's only if he and his horse make it out of the barren plains alive. But just as it looks like Paul's luck has finally run out, he stumbles upon an ailing Cheyenne warrior sprawled on a small island in a dry gulch.
