With his brother now dead, Vartanian is determined to bring the rapists to justice. Alex Fallon's family fell apart when her sister was murdered 13 years ago. Now, with her stepsister Bailey missing, history seems to be repeating itself. When Vartanian meets Alex and realises that her dead sister was one of the girls in the photographs, he begins to believe that the rapists may have been involved in Bailey's disappearance. Vartanian and Alex must confront their pasts head-on if they are to find Bailey before it's too late . . .
