The Cheater(1920)

Lilly Meany has grown up amongst charlatans, including her father. She decides to become a faith healer, and her first victim, a rich hypochondriac woman, is easy enough to "cure." In fact, the woman's so happy with Lilly, now calling herself Vashti Dethic, that she recommends her to her nephew, Judah, Lord Asgarby, who has a crippled sister, Eve. The little girl gives Lilly so much innocent trust and love that she actually is able to walk for the first time ever.
