Autumn Reiniger expects something special for her twenty-first birthday. Her father signs up Autumn and five friends for an ultimate urban reality game. It's a high-priced version of cops and robbers, played with fake guns and fast cars on the streets of San Francisco. Edge Adventures alerts the SPFD ahead of time so the authorities can ignore the squealing tires and desperate cries for help. This is convenient for the gang of real kidnappers zeroing in on their target and a mammoth payday.
