On their expedition they determine that they are, in fact, on a deserted island and decide that they need to find food.The three boys find a pig, which Jack prepares to kill but finally balks before he can actually stab it.During an unnamed time of war, a plane carrying a group of British schoolboys is shot down over the Pacific.
When Simon, the only boy who has consistently helped Ralph, leaves presumably to take a bath, Ralph and Jack go to find him at the bathing pool.
But Simon instead is walking around the jungle alone.
When the boys return from their expedition, Ralph calls a meeting and attempts to set rules of order for the island.
Jack agrees with Ralph, for the existence of rules means the existence of punishment for those who break them, but Piggy reprimands Jack for his lack of concern over long-term issues of survival.
Piggy and Ralph fight once more, and when Ralph attempts to assert the rules of order, Jack asks rhetorically whether anyone cares about the rules.
Ralph in turn insists that the rules are all that they have.
Piggy blames Jack for letting the fire die, for he and his hunters have been preoccupied with killing a pig at the expense of their duty, and Jack punches Piggy, breaking one lens of his glasses. Ralph becomes concerned by the behavior of Jack and the hunters and begins to appreciate Piggy's maturity.
He calls an assembly in which he criticizes the boys for not assisting with the fire or the building of the shelters.
Jack continues to hunt, while Piggy, who is accepted as an outsider among the boys, considers building a sundial.
A ship passes by the island but does not stop, perhaps because the fire has burned out. Bash her in" in celebration of the kill, and they perform a dance in which Maurice pretends to be a pig and the others pretend to attack him.
