After three years cloistered in a convent in New England, the newly minted 23 year old Sister Theresa has been sent to the distant, wicked town of  Hathian. Originally to aid in the redemption of the city , she was soon to learn on arrival that the Church had once again washed their hands of modern day Sodom. She is marooned here, unable to return to the convent or have assistance from other clergy in the area. The naive nun will soon learn whether the vows of obedience, chastity and poverty can save her in the city of debauchery.
