After Henry's girlfriend Val leaves him and transfers to another school, his grief begins to manifest itself in bizarre ways. Cause and effect, once so reliable, no longer appear to be related in any recognizable manner. Either he's hallucinating, or the strength of his heartbreak over Val has unhinged reality itself. Henry decides to run away. If he can find Val, he thinks, everything will make sense again. So he leaves his mother's home in the suburbs and marches toward the city and the woman who he thinks will save him. Once on the George Washington Bridge, however, a powerful hallucination knocks Henry out cold. When he awakens, he finds himself kidnapped by two strangers--one old, one middle-aged--who claim to be future versions of Henry himself. Val is the love of your life, they tell him. We've lost her, but you don't have to.
