Synopsis:
Al Pratt joins several classmates on a trip to a dude ranch. Truck plays a trick on him by giving him a spirited horse. While Al is trying to slow the horse down, the other students encounter two escaped convicts. The crooks switch clothes with Truck and Jack, then begin chasing the girls on horseback. Al dons his Atom costume and runs down the convicts. The police pick up Truck and Jack in the prison uniforms. Al helps get them released, despite the dirty trick they played on him.
