Rio Grande Patrol (1950)

"Breath-taking thrills and roaring action on the lawless Border...with Tim on the side of the U.S.A pledged to destroy a smuggle-gang and their machine-gun traffic in death!"

Fowler is smuggling guns across the border and his buyer is the outlaw Bragg. The guns are hidden in the luggage of the girls that come to work in his saloon. Border guards Kansas and Chito, along with Mexican Captain Trevinom suspect them and they are trying to find the guns.
