An affecting boy and dog story, superior in authentic details about pheasant shooting, hunting dogs and their training. Eleven-year-old Bob Armitage, whose father works for the Mattie Gun Club, dreams of owning a gun and dog of his own. It is through the shrewd and stern old head guide and dog trainer of the Club, Al Doane, however, that Bob not only wins a gun by winning a junior trapshooting contest, but earns a chance to carry for Doane in the field. It is when he is with Doane, that Princess, the scraggly setter, is discovered, and purchased by Al. The wily setter with the great heart soon wins Al's affection and admiration and when Princess is shot accidentally by a wealthy and disagreeable ""sport"", Al grimly agrees to destroy the now gun-shy dog. Bob, however, pleads for a chance to break her, and the careful, early training of Doane, the patience and devotion of the boy, and the spirit of Princess result in a triumphant win in a climactic field trial. A sharp, clean style with a know-how and appreciation for the excitement of the hunt.
