Brett Cassidy, professional gunfighter, has hung up his guns for the peaceful life of a trapper, but one day he receives an urgent letter from a beautiful young widow. The settlers in Lonesome Valley need him. Cheyenne war smoke is rising, and a greedy saloon owner and his hired guns are making life hell for the widow and her friends. Strapping on his guns for one last time, Brett rides to help the homesteaders in their hour of need. But he's alone and faces a stacked deck in the final showdown in the Last Chance Saloon.
A twin-gun-totin gunfighter with a draw faster than lightening lays his life on the line to protect small-time homesteaders against the evil crooked businessman who had dreams of taking over the whole town and region.
As a sideline, he prevents an Indian uprising by rescuing eight Indian maidens from the crooked businessman who was forcing the girls to work in one of his brothels.
Oh, and he also won the heart of a beautiful young widow.
