A group of English schoolboys find themselves stranded on a desert island after their plane crashes over the Pacific. Those who survive the crash elect Ralph, one of the oldest boys, as their leader.
Ralph argues that the group's main goals should be to have fun, survive, and maintain a smoke signal to catch the attention of the outside world and get rescued.
The boys quickly lose interest in the day-to-day tasks Ralph wants them to perform, like building shelters. Instead of working, they spend their time playing and hunting pigs.
When Jack defies Ralph's authority, the boys degenerate into a savage tribe. They set fire to the island in an effort to drive Ralph out of hiding. A British warship, seeing the smoke, stages a rescue. Ralph and the other children are saved
