The boys accept the offer of a vacation - but doesn't realize that the activities during this vacation involves catching and taming wild horses.

They and their friend, Bronc, check into a boarding house near where the horses are, and meet some people whose coach has broken down. Among them is Beegee, a woman on the look-out for a husband, and who takes a good look at both Heyes and the Kid. And then there's the very religious man with a sister who has a crush on the Kid.

But the boys must also battle wits with a ranch owner who thinks that the horses walk on his land. Prhaps the only solution is to shoot him to stop him from stealing ""their"" horses?
