Fast and sure with a gun, Ethan Torregrossa was a town tamer. In one skirmish he was sided by Hank Burr, who was passing through and chose to help. Now Ethan is on the River Hawk, on his way to Stillwater, California in response to an urgent message from Hank. But a shot from ambush on the deck during a thunderstorm pitches him into the roiling river. Injured but swimming safely to shore, he finds that he has lost some of his vision and much of his memroy, but for an unaccountable urge to head west and the blurred name of Stillwater on an envelope in his pocket. Hank Burr, meanwhile, has become the victim of treacher, leaving the Burr Stage an d freight LIne in the hands of his younger sister, Rona. She's convinced that all their troubles, including Hank's death, have been caused by one man. But what can she do about it?
