Autumn Reiniger expects something special for her 21st birthday. Daddy’s already bought her the sports car, the apartment, and admission to the private college where she parties away her weekends. Now she wants excitement, and she’s going to get it. Her father signs up Autumn and five friends for an “ultimate urban reality” game: a simulated drug deal, manhunt, and jailbreak. This is convenient for a gang of real kidnappers zeroing in on their target and a mammoth payday.

On a chilly February night, during a screening of Psycho in midtown, someone sunk an ice pick into the back of Chanel Rylan's neck, then disappeared quietly into the crowds of drunks and tourists in Times Square. To Chanel's best friend, who had just slipped out of the theater for a moment to take a call, it felt as unreal as the ancient black-and-white movie up on the screen. But Chanel's blood ran red, and her death was anything but fictional.
