1996: Ventura, California. 32-year old supermarket clerk Diana Haun thinks she's met her soul mate in co-worker Michael Dally when the two start a steamy affair. But, there's one thing standing between her and a "happily ever after" -- Michael's wife, Sherri. Diana will do whatever it takes to get Sherri out of the way. And in Northport, Florida in 2010, a mistress "sex slave" goes off the rails when her "master" of 13 years tries to leave her for good. Some attractions can be fatal when a mistress turns into a Monstress.
