David Webster escapes from prison after 15 years, having been framed by Fletcher Burton, a prominent businessman. He hides out with Li Fang, a Chinese politician and former friend of Webster's. In order to move about the city undetected, he disguises himself as a cripple, dragging himself about on a pair of crutches. At a local mission, he meets his daughter, a young girl known as "The Angel Lady" because of her many kindly deeds and good works. She befriends the cripple, unaware of his identity, and the two play songs together, he on violin and the girl on piano.
