Five hundred years from now, the necessity of population control and a preference for male children has resulted in a shortage of women. Down from the Appalachian Mountains, comes Tory White, an unusually tall and muscular young woman. Unable to read, she is deceived into signing a lifelong contract as a concubine. Entirely unsuitable for the position, she soon finds herself slotted for the 'beds', where few girls live beyond a month. Yet, her honest and forthright manner charms the head of security into saving her and sets her upon a path in which she becomes the 'heart' of the world and the savior of man's future.
