Middle-aged Bill Thompson returns to his ranch with his much younger bride, Janice, and her supposed brother Lon. When Thompson's son Dan disapproves of the surprise re-marriage of his father, the latter orders him off the ranch, without his promised horses, despite the pleas of ranch foreman Jimmy Wakely and cowhand "Cannonball". Janice and Lon, in reality sweethearts, plot to gain Thompson's rich holdings.
