Synopsis
A lavish country party that should have been the best night of their lives unexpectedly begets a shocking cycle of violence for a confident career woman and her handsome young love interest in this brutal and unforgiving thriller starring Gillian Anderson and Danny Dyer. Adam (Dyer) is just getting his career off of the ground, so when the beautiful, older, and much more professionally experienced Alice (Anderson) invites him to a party, he readily accepts. Upon arriving at the classy soirée the pair immediately discover that they share an exhilarating sense of sexual chemistry, eventually wandering off alone for some highly charged sex. Still reeling from their earth-shaking bout of lovemaking, Adam and Alice speed down a quiet country road and suddenly find themselves thrown into the middle of a vicious attack in which both are severely injured. But their physical scars don't run nearly as deep as their emotional scars, and before long Alice becomes overtaken by her drive for vengeance and determined to make her tormentors pay for their violent transgression. ~ Jason Buchanan, All Movie Guide
