Published under his pen name Richard Bachman, The Long Walk is described as a dystopian thriller centering on the contestants of a grueling and vicious annual walking contest that requires 100 boys to keep a certain pace without stopping. If they do, they receive a warning. If it happens again, they are eliminated — and killed. Related StoriesMoviesAna de Armas...
