Lord of the Flies opens with a plane full of British schoolboys crashing on a deserted tropical island without any adults. Two of the boys, Ralph and Piggy, discover a conch shell on the beach, and Piggy realizes it could be used as a horn to summon the other boys. Once assembled together two dominant boys emerge during the meeting, Ralph and Jack. Ralph is voted chief and states two goals: have fun, and work towards a rescue by maintaining a constant fire signal. The boys split up, one group would maintain the constant fire and the other boys would be the hunters, they all helped each other.
For a time, the boys do work together but soon Jack becomes bored and resentful of Ralphs superior role and he leaves the group with the hunters to a new tribe. Possessing different goals and different sets of ethics, the boys divide into two tribes. Eventually, Ralph’s side of reason and rationality gives way to Jack’s tribe of hunters, and the boys sink deeper and deeper into a life of violent savagery. As Jack quickly starts to recruit more and more boys this soon leaves Ralph and Piggy isolated. Around the same time, many of the younger boys begin to believe that the island is inhabited by a monster, referred to as "the beast".
Jack’s “tribe” of hunters become in over their heads and savages. Simon, who had "cracked" had gone off by himself and finds the head of the hunter’s dead pig on a stick, left as an offering to the beast. Simon envisions the pig head, now swarming with scavenging flies, as the "Lord of the Flies" and believes that it is talking to him. Simon hears the pig identifying itself as the real "Beast" and disclosing the truth about itself, that the boys themselves "created" the beast, and that the real beast was inside them all. Simon also locates the dead parachutist who had been mistaken for the beast, and is the sole member of the group to recognize that it is a dead body instead of a sleeping monster. Simon attempts to alert Jack's tribe that the "beast" is nothing more than a corpse. While trying to tell Jack's tribe of this, he is mistaken for the "beast" in the darkness, and Jack's tribe kills him.
Jack's tribe then raids Ralph's camp to steal Piggy's glasses – the glass lenses being the only source of starting a fire. Ralph's tribe journeys to Jack's tribe to try to retrieve the glasses. In the resulting conflict, Roger drops a boulder, aiming at Piggy. Piggy is
