Lord of the Flies (1990)

After a plane crash in the ocean, a group of military students reach an island. Ralph organizes the boys, assigning responsibilities for each one. When the rebel Jack Merridew neglects the fire camp and they lose the chance to be seen by a helicopter, the group split under the leadership of Jack. While Ralph rationalizes the procedures, Jack returns to the primitivism, using the fear for the unknown (in a metaphor to the religion) to control the other boys, and hunting and chasing pigs, stealing the possession of Ralph's group and even killing people.
