 Tom Wade (Tom Tyler), better known on the border as "Cheyenne Tommy", is an operative of the Cattleman s Protective Association, who poses as an associate of rustlers and outlaws in order to gain their confidence and end their activities. When on the trail of a pacticularly daring and dangerous rustler gang, Tom plants his pretty assistant, Sally Lane (Lucile Browne), on a ranch owned by Rollins (Theodore Lorch), who Tom knows to be the brains and leader behind the rustlers. With his other aide, "Dopey" Andrews (Jimmy Fox), Tom pulls a stage holdup and gets away with $10,000 sent to Rollins as payment for stolen cattle. Sally s attempts to communicate with Tom lead her to being imprisoned but Tom, with "Dopey s" aid gets into the stronghold posing as a wanted outlaw.
