A bandit who robs both Americans and Mexicans is causing each side of the border to blame the other. Hoppy has to settle matters.

Hoppy is sent for to see if he can find the outlaw gang working both sides of the border. The gang leader, sometimes dressed as Hoppy and sometimes as Gonzales, has the two sides suspecting each other. But finding an old wanted poster, Hoppy sets a trap.—Maurice VanAuken <[email protected]>

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.—Les Adams <[email protected]>
