A man named Clay barely survives a car-bombing engineered by his half-brother, Vincent. Clay is dressed in Vincent's clothing and carrying Vincent's identification, so the staff of the Phoenix Medical Center takes him for his half-brother. Damaged beyond recognition and stricken with amnesia, Clay attempts to reconstruct a life that was never his own. Gradually recognizing that he might not be the person he is believed to be, Clay must take action--either to reclaim the identity he has lost or to embrace his new one.
