Jimmy Wakely and his sidekick "Lasses" White run into trouble as they attempt to hire some cattle cars on the Cattleman's Railroad to take their herd to market. Rancher Joseph Colton has bought up all the cattle cars and intends to purchase the penniless line from principal stockholder Gywnn Randall. She is eager to sell to Colton but doesn't realize that he intends to force all the ranchers out of business once he has control of the line.
