A group of boys is crashed on an island. A boy named Ralph blows into a shell to unite all survivors and he is named chief. All boys band together to make a signal fire and burn part of the island and another boy on accident.
A boy named Jack begins to question Ralph's leadership. He despises Ralph and is trying to take power. He does this by making all other boys question Ralph. Jack's leading argument is that Ralph did not want to kill a supposed beast on the island and was afraid.
Jack leaves the group and forms his own tribe. In this tribe he is the self-proclaimed leader. He does this because as the boys spent time on the island Jacks humanity is slowly depleting.
All children join Jack's group, including Ralph and his only true friend Piggy, and have a fire to cook a pig. at this fire a boy named Simon crawls in to tell the others that their beast is actually a dead pilot. While in the middle of a primal dance the boys trample and kill Simon, hiding his body in the ocean.
Jack sets fire to the island trying to kill Ralph unsuccessfully and Ralph finds a man. The man saw the fire from his boat and showed up to rescue the boys. He assumed they were playing war and still had all of their humanity.
The man, a Naval Officer, finds the truth out and is shocked. He cant believe a group of children lost all rules of society in such little time. The boys, overwhelmed with the thought of freedom from their dark selves, begin to cry. While they cry the Naval Officer turns around so they can regain their composure. The children are saved.
