Survivor

This is about a group of students who are in a plane crash and have to survive in the wilderness near Peru with the other survivors, but while they are there, they realize that the forest they landed in was a nuclear waste area that the world decided was despendable and used for hiding the governments mistakes. Because of the toxins and radiation from the thrown away weapons, everything is mutated and larger than the things in real life, so they also have to survive much harsher environments than what they would normally have had to go up against.
