Bret and his buddy Waco Williams (Wayde Preston) ride straight into trouble in Bent City, where they are suspected of being cattle rustlers.

Hired to protect a cattle drive, Bart dutifully chases Indians — while a masterful swindle takes place right under his nose.

On their way to Denver, Beau and Bart Maverick pick up $6,500 in a poker game at Stop Gap. They decide to wire the money to Denver through the Hulett Telegraph Company. They discover the company is a fake and that the telegraph line leads to a cave two miles away where the crooks stash the customers' money and send phony messages in return. The cousins devise a scheme to recover the money and put the company out of business.
