The story is set in the late 1800s in Utah and follows the character of Jane Withersteen, a wealthy Mormon woman who defies the expectations of her religion and community by refusing to marry one of the elder churchmen. As a result, she becomes a target of persecution and violence from the Mormon community, and her only hope for protection lies in the hands of a gunslinger named Lassiter, who has his own reasons for hating the Mormons. As Jane and Lassiter work together to fight against the corrupt religious leaders and their enforcers, they uncover dark secrets and hidden agendas that threaten not only their lives but also the very fabric of their society.
