Over the past 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 relinquish modern goods, of plastic and metal for example, replacing them with leather, wood and flint, like in Stone Age. Then, without tents, flashlights, sleeping bags, knives or matches, and dressed and equipped only with what they’ve made themselves, they go into the wild for a month to simply try and survive. No one ever comes back the same person from this kind of journey. This documentary isn’t merely an adventure into some of the most beautiful landscapes of America. It is also, and more specifically, an intimate portrait of each of the ten participants, all from different social, professional and geographical backgrounds. As this unique experience unfolds, they learn about themselves, and maybe find answers to questions we all ask ourselves: Where is this “consumer” world we live in heading? What should our essential values be?
