Mollie, an Irish immigrant, and popular courtesan becomes rich while operating a successful brothel in Prescott, Arizona during the 1870's. After being forced to leave Prescott through political collusion between the Ladies Morality League and the territorial governor, an array of enigmatic characters and a streak of turbulent circumstances turn Mollie's life topsy-turvy. During the chaos that follows, Mollie almost dies when she is wounded by Indians; she fends off an assault attempt; adopts a teenager to save the girl from a life of prostitution; quits the brothel business; returns to her homeland in Ireland to join her family; and becomes a successful legitimate business woman. She finally finds love with a man she met aboard ship during the trans-Atlantic crossing to Ireland.
