When Mark Ryan came to Yellowstone, he was a lonely frightened man running from death, though his soul had died five years before. From another direction rode three former troopers of the Seventh Cavalry, driven by a single idea: to kill him. There was an aftermath of the Custer story and it happened in Yellowstone.
