For twenty years, Lynx, a 45-year-old woman, has lived in the forests in North-West America. She gradually abandoned modern civilization and learnt how to live using prehistoric survival skills. Every year, she passes on her knowledge and skills to a group of people from all over the world. For five months, they learn how to live without tents, flashlights, sleeping bags, knives or matches, and dressed and equipped only with what they’ve made themselves, they go into the wild to simply try and survive. No one ever comes back the same person from this kind of journey.
