Plot.
As described in a film magazine, Phineas Dobbs (Mix), cowboy and dairyman, becomes rich when oil is discovered on his land. His first thought is to give a party with the whole town as his guests. The party is at its height when a mysterious and beautiful young woman with two frock-coated escorts alight from a nearby stalled train who are menaced by the town badman. Disposing of the bad man in his best style, Phineas takes to the open country on his horse. The train passes and the lady throws him a note from the window, asking him to follow and rescue her. His quest takes him to San Francisco and thence to an estate in the San Mateo hills, where a secret society of foreign noblemen are seeking to force the young woman to marry one of their members. Her father is held prisoner and his life is to be the price of her refusal. Phineas mixes in and, with the help of his trusted steed, effects the rescue of the young woman, who turns out to be a princess and her father a king. Sometime later, after he has returned to the ranch, the young woman appears and they are married.
Preservation status.
