Michael is stranded on an island, after falling off of his boat.
While exploring the island, he hears some strange noises. He assumes that they are being made by gibbons.
He lights a fire to signal for help.
He meets Kensuke, who is very angry with him for setting a fire. He gives Michael a set of rules to follow. As long as he follows these rules, Kensuke would keep him alive by giving him food and water.
Michael has no choice but to sleep in a cave. Every night he gets attacked by mosquitoes, that give him terrible bites. He dreams about going back to his parents while he sleeps.
Kensuke provides Michael with a sheet to help him sleep at night.
