Ever since her family died in a plane crash, Esther Robinson has been living in an orphanage, never the same since. When a couple adopts her, she finds out that they are not who they seem to be. The couple adopts children, starting at the ages of eight to twelve, with blonde hair and blue eyes and abuses them viciously, turning them into brainwashed assassins to do their dirty work. Will Esther be able to escape before it's too late? Or is she doomed to be a mindless killer forever?
