If you step off the path, you die. Race… or die." 　　Many will start but only one may cross the finish line alive. Eighty individuals are chosen by an anonymous being, who instantly disappears from where they were to appear on a path, prepared for the race. 　　Each person hears the same message in their own language, with their own voice, and instantly needs to race and survive.
