Wild Trek

So, jumping right into things and skipping the hook, this naturalist called Trigg Antray and his pilot Tom Garridge crash land in a mysterious, a wild, and unpopulated mountain range named the Caribous. A trapper named Link journeys in to rescue them with his combo wolf/dog companion. They find evidence of previous explorers, and eventually find the two crashed men Trigg is hopeful and cheery, but Tom Garridge goes completely insane and steals pretty much everything they own. Can they survive with only a jackknife and the clothes on their back?
