The boys' plane crashes, and they are stranded on a deserted island. When they all swim ashore, the boys find a conch shell and use it to call to the others.
A struggle for power begins. Most of the boys, particularly Ralph, attempt to create order. However, some of the boys, especially Jack, do not want to listen to Ralph.
As Ralph struggles to maintain order, the lack of adults, laws, and structure creates chaos among the boys. Rumors of a monster on the island begin to circulate. Jack and his hunting party vow to kill the monster.
Piggy is killed, and the faction led by Jack has taken on a savage, ritualistic mentality. Ralph goes to confront them.
Jack and the hunters turn on Ralph and begin to hunt him.
Ralph runs to the beach to escape Jack. There, he encounters a British Naval Officer. As he attempts to tell him what has happened, he breaks down into tears. When the other boys arrive, they also begin to sob.
