There is an island in the middle of uncharted waters thats been lost in time. One day a group of planes which had been passing over these uncharted waters crashed within the same month, most passangers died and few made it through the wreckege and ended up on the island barely alive. Everyone was persumed dead when the remains of the airplanes were found by the mainlands of the rest of the world, but no sign of the mysterious island on which the survivers found themselves on.

They run into a tribe of people armed with bows and arrows, spears, daggers, swords, knives, etc. And are taken captive to see the Chieftan. M/C- the chieftans daughter- manages to convimce him to allow the strangers to live and earn their stay on the island by putting them through a series of trials and tribulations in order to earn their stay. Eventually M/C's interest grows in the group of survivors and decides to secretly help them in their survival on the island.
