A plane crashes in an island. One half of the plane crashes on the north side of the island the other on the south. In the middle of an islnad is a huge lake where a waterfall dumps it's waters. Everything is jungle like and there are all types of animals here. On the edge of the island is beach like (like above^^) The island is no where in corse of a usual plane so their chances of getting rescued is very slim.
While PRing the northners and southners will meet.
