What would you do if you couldn't remember... who you were? where you lived? or what you might have done? Rush hour, Grand Central Station. Aaron Clifford stops dead in his tracks, commuters swirling around him -- but he doesn't know he's Aaron Clifford. He doesn't know who he is at all. No matter how hard he tries, he has no memory of why he is there, where he came from, or where he's going. It's impossible ...maddening...but its true.
