Ralph, Piggy, and the other boys are stranded on an island in the Pacific. Most of the boys elect Ralph as the chief while Jack, embarrassed by this, makes the people who voted for him hunters.
Jack and his hunters fail to catch a pig and didn't get a fire going when a ship passed which deeply upsets Ralph. This causes a divide in ideology between Jack and Ralph on how to run the island.
Jack, embarrassed at losing an argument about being chief yet again with Ralph, splinters off with his hunters to make his own tribe located on Castle Rock. Simon, mistaken for the beast, gets killed and beaten by everyone including Ralph and Piggy.
After Piggy dies from Roger catapulting a boulder onto his head, forcing Ralph is forced to hide from Jack's tribe who want to kill him as they burn the island down.
Ralph runs to the shore and meets a naval officer who arrives to the island after seeing the smoke. The boys begin to cry as they recollect how savage they've become.
The naval officer, who is a little embarrassed by his words, looks at his cruiser in the distance showing how similar there circumstances are in their battles.
