Dolores Gardner

Ranger Dave Mannion is deprived of his badge for allowing the notorious Braxton gang to drive diseased cattle past his border patrol. He suspects Eric Prang to be a spy for the gang and sets out to prove it.

Jim Wesley returns from college with a silk shirt and eastern ways, earning the contempt of the cowpunchers on his father's ranch. With a little hard riding and fancy roping, however, Jim proves himself to be a regular guy. Jim's father is involved in a dispute over water rights with Adam Grayson, a neighboring rancher, and the two men decide to settle the disagreement by a marriage between Jim and Grayson's daughter, Marguerite. The young people refuse, but when Marguerite is attacked by a rejected suitor, Jim comes quickly to her rescue.
