Tim Hall wants to remember. He knows it will be painful, reliving the car accident that took his wife and his memories, but not knowing the past is horrific. So he volunteers for a medical experiment that might bring it all back. Then he awakens from a blackout that lasted several days and he is certain that he is being shadowed. Is it paranoia? Did he briefly remember something that worries people? He is smart enough to know it is not paranoia if they really are after you.
