Who Is to Blame?(1918)

Charmed by the bright smile of Taro San, a Japanese rickshaw boy, Grant Barton takes the young man to the United States as his valet. Grant marries Marion Craig, but when she departs for California to visit her sick mother, he becomes enamored of Tonia Marsh, a vamp. Marion discovers them together and leaves Grant, whereupon Taro resolves to help his kind employer out of his difficulties. Persuading Tonia that he is a member of the imperial family of Japan, Taro pays court to the adventuress, and when Grant finds them in each other's arms, he immediately fires Taro. Grant and Marion are reconciled, while Taro sadly returns to Japan.
