The kidnapping of a young girl propels her mother into a web of conspiracies.

An American occult novelist battles to save the soul of a young girl from a group of Satanists, led by an excommunicated priest, who plan on using her as the representative of the Devil on Earth.

Rosie Nell, a woman of disreputable dance halls in early lawless California, is wrongly charged with the murder of one of her fellow entertainers. Because her daughter, who knows nothing of her mother's station in life, is to return the next day from her school in the east, Rosie is granted three days of grace to be spent in company with her daughter at a nearby cabin. The three days begin happily enough, thanks to the serenades of heroic bandit Alvarez and the poetry of romantic Randolph. But Bagley, the dance hall manager, has seen the daughter and has determined to make her his own.
