The Spirit of Good (1920)

Deserted by her husband, showgirl Nell Gordon ventures West to a small desert town where she works in Chuck Lang's dance hall. When Reverend Josiah Calvin comes to town to spread the gospel, Nell and Lang, feeling their livelihood threatened, scheme to put the reverend out of business. Nell pretends to join forces with the reverend and, while fervently singing a hymn, she converts an embittered and disbelieving Neal Bradford who, inspired, falls in love with Nell. The singer is so touched by Bradford's faith that she joins forces with him and the reverend against Lang. After several skirmishes, good overcomes evil and the two converts begin a new life together.
