Having met only days before, the young, doe-eyed Crystal Vargas elopes with a dashing Brit named Duncan Douglas who appears to be everything she's ever wanted. Without realizing it, her desperation to be loved plays well into the hands of her new husband, a cunning sociopath in need of an American bride to help him maintain appearances. When Crystal's sister, Lyssa, notices suspicious changes in her sibling's behavior and her application for her security clearance is denied, Lyssa hires a private investigator to look into her mysterious brother-in-law. While the truth might prove her right, it might also cost Crystal her life.
