Peggy Winston, the boss of a lumber camp left to her by her father, is loved by all the "jacks" of the camp. When Clayton Hargis, the son of a millionaire ship builder visits to contract for the camp's entire output, Peggy, deeply affected by him, rescues him when he falls into dangerous waters, but Clayton remains ignorant of her affection. Peggy accepts the invitation of Clayton's sister to join them in the city, and after trading her corduroys and spiked shoes for silks, blossoms into a beautiful woman. Heartbroken when she sees Clayton's fiancée embrace him, Peggy leaves and lives a week in the city after pawning her clothes. In Peggy's absence, the title to the camp is taken over by a friend of Clayton's. The friend and Clayton, who now realizes that he loves Peggy, search for her at the camp. After the hostile lumberjacks lock them in a cabin and plant dynamite underneath it, Peggy arrives, quells the riot, and saves them.
