The old professor, accompanied by his daughter and the young professor, arrive home from a trip, bringing with them a full-blooded young Indian, upon whom the old professor intends making certain experiments. Jerry has been informed of their intended homecoming and is at the train to meet them, but receives anything but cordial greeting from the old professor, who intends marrying his daughter to the young professor. Jerry and the girl, however, are not discouraged and try to plan a method of meeting. Chance favors Jerry by placing him in possession of the Indian's "other clothes'' and the girl, supplying the paint from a box of watercolors, he is soon the actual duplicate of the real Indian. They then inveigle the Indian into the wine cellar and taking advantage of his taste for "fire water,'' soon have him enjoying what he believes is his "happy hunting grounds." The only trouble with the plan is that he does not remain where they put him and "leaves the reservation." Then things happen and keep on happening, everyone, including even the girl, taking Jerry for the Indian, or the Indian for Jerry, until the aid of the law is called upon to straighten out the tangle, and then even the law gets tangled.
