When their plane crashes, 25 schoolboys find themselves trapped on a tropical island, miles from civilization. At first, they welcome their new freedom. But soon they discover that trying to survive is anything but fun and games. Ralph and his friend, Piggy, organize the boys according to the values of the civilization they left behind. Working together, they have a better chance of getting food, getting water and getting rescued. But another boy, Jack, embraces the savagery of his new surroundings. One by one, he lures the other boys into his camp. Donning war paint and spears, everyday life becomes a spectacle of sadistic games, rituals and punishments.
