Collegian Angelica "Trix" Varden, willful daughter of William Varden, after a midnight spread of lobster and ice cream, has a dream about an adventure on her father's ranch involving her horse Beverly, one Jack Norton, and Buck Barlow's gang of rustlers. She is expelled from school and returns home to find a handsome new foreman, who is none other than Jack Norton. Trix's curiosity is aroused by her dream, and she finds evidence of rustlers. Barlow shows up, and she locks herself in a cabin and sends Jack's horse, Star, for help. Jack finally defeats Barlow in a fight, and the two horses "realize" that they now have both a master and a mistress.
