It's April 1944 and Ellery Queen has been working for the military making films in Hollywood. Driving through Death Valley on his way home, his car breaks down. Stumbling over a rise in the desert, he encounters an odd man who seems to come from an earlier time, and is welcomed into his community as a sort of prophet. Queen must root out a growing corruption while operating within the limits of an alien world and comes to the realization that evil can invade the most guarded of people's hearts and societies.
