Rin-Tin-Tin is saved from the beatings of a trapper by Ed Nolan, a shiftless trapper himself, and 'Rinty" follows Nolan home to his cabin but refuses to enter. Nolan takes him to the home of Mary Mallory, the girl he has failed to win as his wife because of his ways, and in their mutual love of 'Rinty," a new understanding is born and Nolan goes to work.
