Hopaloing Cassidy (
William Boyd) and his sidekicks CAlifornia Carlson (
Andy Clyde and Breezy Travers (
Jay Kirby) are sent by Texas Ranger Captain John Hawkins (
Jack Rockwell) to the Mexico hacienda of Don Tomas Gonzales (Antonio Moreno (I)'), in an attempt to discover who has been raiding on both the Texas and Mexico side of the border. During a raid on the Mexican property, somebody resembling Cassidy is seen as the bandit leader, and in the same way, during an American raid, Gonzales is recognized. Cassidy discovers the ruse, realizing that someone has been impersonating both men---someone in the Gonzales household who has access to both his and Gonzales' clothes and horses.
