For two years after Cassie had helped solve the case of the mysterious 'Rose Killer,' all was well in her life. She got her friends back, and things went back into place, just as they used to be. She's studying criminology in the University, and she finally feels like nothing can ever go wrong in her life again... Or so she thinks. Another mystery comes knocking at her door, one she hoped would never visit, one she feared for a long time, one that tormented her, but most of all, one she's too weak to resist. She receives an image, one of her and her childhood best friend , Avril, who had been mysteriously and brutally murdered when they were kids. She knows there's a reason why someone sent her that image, someone is trying to tell her something, or maybe even threaten her. Her obsession returns in full force, and she wouldn't rest until she uncovers the mystery behind Avril's murder.
