"Now ladies and gentlemen ... an amazing trio of trick riders, who will thrill you with daredevil riding and spectacular feats -the Three Tuckers!" Suddenly it is Peggy's turn to ride. No time to think, no time for anything but get ready, get set, "Heads Up!"
How wonderful to be a part of the Tucker act! How comforting to be wanted by them - the first family Peggy has ever known. Will she be able to stay with them? Will she be allowed to keep Chief, the horse she alone can manage? Or will Mr. Mac, the trainer Peggy works for, succeed in his dishonest plan?
