Below the Border (1942)

"The Rough Riders-That Triple Threat Trio Is Back Again! Fighting is the Business! These Reckless Buckaroos Live to the Tune of Leather and Lead! Blazing their Brands on the Lawless West!"

Scully has forced Joe Collins who works on the Garcia ranch to give him information so his men can steal the family jewels. But the Rough Riders are on the job. Buck poses as a wanted outlaw to get into the gang, Tim as a cattle buyer, and Sandy is collecting information as the saloon janitor. As usual they pretend not to know each other.
