In a dystopian near-future, America has fallen on hard times. Sixteen-year-old Ray Garraty is about to compete in the annual match of stamina and wits known as the Long Walk. One hundred boys must keep a steady pace of four miles per hour day and night, without ever stopping. The winner gets 'The Prize' - anything he wants for the rest of his life. But the rules of the Long Walk are harsh and the stakes could not be higher. There is no finish line-the winner is the last man standing. Contestants cannot receive any outside aid whatsoever. Slow down under the speed limit and you're given a warning. Three warnings and you're out of the game - forever.
