Prequel to the hit 1999 teen-drama 'Cruel Intentions'. Sebastian (Robin Dunne) has been kicked out of yet another private school and is sent home to live with his father and stepmother in New York. Here he meets his beautiful and manipulative step-sister Kathryn (Amy Adams), who will do anything to make his life a misery, especially since he has fallen for the innocent Danielle (Sarah Thompson). Kathryn tries everything to seduce Sebastian, even when his new girlfriend is around. This temptation causes many problems for Sebastion, whose past track record in relationships has not been the most honest.
