CHAPTERS 1-6
A plane carrying a group of boys crashed on a deserted island. They looked for each other and made groups with different tasks.
Ralph, the leader, sends a group to explore, and one to hunt and keep a fireplace going for a boat to see them. Ralph complains about the attitude of the other boys, they get excited about the ideas that they have but then they don't do anything to accomplish them.
Jack, the leader of the hunting team was obsessed with catching a pig so he went hunting but he let the fire go out. Ralph and Piggy saw a boat getting close to the island but as they didn’t have any fire the boat went away. Jack came back with his pig but everyone except for the hunting team was angry at him. Ralph calls for a reunion where he tells everyone to be more responsible about their tasks, then he mentions that there are no beasts or monsters in (on) the island but a littlun (little one) says otherwise, he says that he has seen one.
Everyone but Ralph, Simon and Piggy went to hunt the mentioned beast. That night, some military planes were fighting, they couldn’t see it because the ones that were in charge of the fire went to sleep. When they got up, they started the fire again, but then they saw a dead parachuter from the fight and mistook it for the beast. They told Ralph and together decided to go and investigate the island.
