Laurel and her husband Mark live a normal life, till one day Laurel suddenly changes. For reasons she can not explain to herself Laurel finds herself with an uncontrollable compulsion to seek out men for sex. One break in her seemingly ordinary existence leads to another, and in an explosive argument with her husband, Laurel is stunned when Mark says their daughter is not his child. Soon, Laurel has been reunited with friends and family she does not remember, and a Dr. Celeste Morrow, who Laurel learns is her sister. Using hypnotherapy Celeste restores Laurel's memories of her real life, identity and purpose. Laurel discovers she is a member of the "Sisterhood", a bloodline of women whose history of seduction and murder reach back over 500 years. The Sisterhood has been waiting for her return, for only Laurel has the skill to assassinate a sinister, Hitlerian madman who intends to rid the world of undesirables and replace them with a perfect race sired with the aid of his harem of perfect women. To stop him, Laurel will have to infiltrate his organization, gain his trust, and ultimately his love. Though Laurel still has doubts, she agrees -– for the Sisterhood holds her daughter as "insurance" that Laurel will carry out the mission.
