Getting involved in a frontier clash between cattlemen and rustlers when a herd belonging to the Bar 20 is rustled, "Hopalong" Cassidy plays a dangerous game. Posing as an outlaw himself, he wins the confidence of the gang through his prowess gambling at the card-tables and his recklessness on the range. To maintain his cover, he even allows "Lucky" Jenkins to be taken to jail, charged with a murder the rustlers had committed. Cassidy's "game" brings results when he realizes that the gambling-hall owner and the foreman of a ranch are identical twins.
