The Border Patrol.

Texas Ranger Bill Storm is sent to El Paso to ferret out a gang of counterfeiters thought to be working there and, on the way, gives a ride to New York socialite Beverly Dix, whose car has been wrecked on the road to El Paso. Bill quickly comes to suspect Earl Hanway and Lefty Waterman of passing bad bills; taking Beverly's father into his confidence, Bill identifies the counterfeiting plant, arrests Hanway and Waterman, and finds himself with his arms full of Beverly.
