The fifth film in the 24-film Range Busters series finds "Crash", "Dusty" and Alibi, on their way to Gopher City to become the town's peace officers. In the saloon, young Jimmy Rowell is losing money in a crooked poker game to saloon owner Bob Harmon. Harmon and his henchman Bart Gill are in reality wanted-outlaw brothers Jim and Ike Breedon seeking revenge against Jimmy and his school-teaching sister Sally as their father, a circuit judge in Nebraska, had sentenced their brother Bud to be hanged. Harmon involves Jimmy, because of his gambling debts, in a robbery of a rancher known to keep large amounts of money at his ranch. The Range Busters break up the robbery, Bart is killed, as is Rancher Fleming, and Jimmy is wounded but escapes. Harmon, setting a trap for Crash, tricks Sally and Jimmy to his hideout, and Crash follows them.
