In the midst of a wartime evacuation, a British aeroplane crashes on or near a separated island in a remote area of the Pacific Ocean. The only survivors are young boys in their middle youth or preadolescence. Two kids– the fair-haired Ralph and an overweight, bespectacled boy nicknamed “Piggy”– discover a conch, which Ralph utilizes as a horn to convene all the survivors to one location. Ralph is positive, thinking that grown-ups will come to rescue them but Piggy realises the need to arrange: (“put first things first and act proper”). Due to the fact that Ralph appears responsible for bringing all the survivors together, he instantly commands some authority over the other young boys and is quickly elected their “chief”. He does not receive the votes of the members of a young boys’ choir, led by the red-headed Jack Merridew, although he enables the choir boys to form a different clique of hunters. Ralph establishes 3 main policies: to have a good time, to endure, and to constantly maintain a smoke signal that might signal passing ships to their presence on the island and thus rescue them. The young boys establish a form of democracy by declaring that whoever holds the conch shall also be able to speak at their official gatherings and get the attentive silence of the bigger group.
Jack organises his choir into a searching celebration responsible for discovering a food source. Ralph, Jack, and a quiet, dreamy kid called Simon quickly form a loose set of three of leaders with Ralph as the ultimate authority. Upon evaluation of the island, the 3 determine that it has fruit and wild pigs for food. The young boys likewise use Piggy’s glasses to create a fire. Although he is Ralph’s only genuine confidant, Piggy is quickly made into a castaway by his fellow “biguns” (older young boys) and becomes a reluctant source of laughs for the other young boys while being disliked by Jack. Simon, in addition to monitoring the project of constructing shelters, feels an instinctive need to secure the “littluns” (more youthful boys).
The semblance of order quickly weakens as most of the young boys turn idle; they give little help in structure shelters, spend their time having a good time and start to develop paranoias about the island. The main paranoia describes an expected beast they call the “monster”, which they all gradually start to think exists on the island. Ralph insists that no such monster exists, but Jack, who has actually begun a power battle with Ralph, gains a level of control over the group by boldly promising to kill the animal. At one point, Jack summons all of his hunters to hunt down a wild pig, drawing away those designated to preserve the signal fire. A ship takes a trip by the island, but without the young boys’ smoke signal to alert the ship’s crew, the vessel continues without stopping. Ralph angrily confronts Jack about his failure to maintain the signal; in disappointment Jack attacks Piggy, breaking one of the lenses of his glasses. The boys subsequently enjoy their first banquet. Outraged by the failure of the kids to bring in possible rescuers, Ralph considers relinquishing his position as leader, however is convinced not to do so by Piggy, who both comprehends Ralph’s significance and deeply fears what will end up being of him must Jack take overall control.
One night, an aerial fight takes place near the island while the boys sleep, throughout which a fighter pilot ejects from his plane and dies in the descent. His body wanders down to the island in his parachute; both get tangled in a tree near the top of the mountain. Later on, while Jack continues to scheme versus Ralph, the twins Sam and Eric, now appointed to the maintenance of the signal fire, see the corpse of the fighter pilot and his parachute in the dark. Mistaking the corpse for the beast, they go to the cluster of shelters that Ralph and Simon have actually put up, to warn the others. This unexpected conference again raises tensions in between Jack and Ralph. Shortly afterwards, Jack decides to lead a celebration to the opposite of the island, where a mountain of stones, later on called Castle Rock, forms a location where he declares the monster lives. Just Ralph and a quiet suspicious boy, Roger, Jack’s closest fan, accept go; Ralph reverses shortly before the other 2 young boys however ultimately all 3 see the parachutist, whose head rises by means of the wind. They then leave, now believing the beast is really real. When they come to the shelters, Jack calls an assembly and tries to turn the others against Ralph, inquiring to get rid of Ralph from his position. Receiving no assistance, Jack storms off alone to form his own tribe. Roger right away sneaks off to join Jack, and slowly an increasing variety of older young boys desert Ralph to sign up with Jack’s tribe. Jack’s tribe continues to draw recruits from the main group by appealing feasts of prepared pig. The members begin to paint their faces and enact unusual rites, consisting of sacrifices to the monster. One night, Ralph and Piggy choose to go to among Jack’s feasts.
Simon, who faints regularly and is most likely an epileptic,   has a secret hideaway where he goes to be alone. One day while he is there, Jack and his fans erect an offering to the monster nearby: a pig’s head, installed on a sharpened stick and soon swarming with scavenging flies. Simon carries out a fictional dialogue with the head, which he calls the “Lord of the Flies”. The head mocks Simon’s notion that the beast is a real entity, “something you might hunt and kill”, and exposes the reality: they, the boys, are the beast; it is inside them all. The Lord of the Flies likewise warns Simon that he is in risk, because he represents the soul of man, and forecasts that the others will kill him. Simon climbs the mountain alone and finds that the “beast” is the dead parachutist. He rushes down to inform the other boys, who are participated in a ritual dance. The crazy kids error Simon for the beast, attack him, and beat him to death. Both Ralph and Piggy take part in the melee, and they end up being deeply disrupted by their actions after returning from Castle Rock.
Jack and his rebel band decide that the genuine sign of power on the island is not the conch, however Piggy’s glasses– the only implies the young boys have of starting a fire. They rob Ralph’s camp, take the glasses, and go back to their abode on Castle Rock. Ralph, now deserted by most of his supporters, journeys to Castle Rock to face Jack and secure the glasses. Taking the conch and accompanied only by Piggy, Sam, and Eric, Ralph discovers the people and demands that they return the important things. Verifying their total rejection of Ralph’s authority, the people capture and bind the twins under Jack’s command. Ralph and Jack take part in a fight which neither wins prior to Piggy attempts once more to address the tribe. Any sense of order or security is permanently eroded when Roger, now sadistic, intentionally drops a boulder from his vantage point above, killing Piggy and shattering the conch. Ralph manages to escape, but Sam and Eric are tortured by Roger until they agree to join Jack’s tribe.
Ralph privately challenges Sam and Eric, who alert him that Jack and Roger dislike him and that Roger has sharpened a stick at both ends, implying the tribe intends to hunt him like a pig and behead him. The following early morning, Jack orders his tribe to begin a hunt for Ralph. Jack’s savages set fire to the forest while Ralph frantically weighs his options for survival. Following a long chase, the majority of the island is consumed in flames. With the hunters closely behind him, Ralph journeys and falls. He looks up at a uniformed grownup– a British marine officer whose celebration has actually landed from a passing cruiser to investigate the fire. Ralph bursts into tears over the death of Piggy and the “end of innocence”. Jack and the other young boys, dirty and unkempt, likewise go back to their real ages and emerge into sobs. The officer expresses his disappointment at seeing British young boys showing such feral, military behaviour before turning to stare awkwardly at his own warship.
