Leaving everything behind to live deep in the woods for over a month, accompanied by wildlife experts. This is the challenge that two families – who did not know each other before this one-of-a-kind reality TV experience – have decided to take on. Kim Pasche, an expert in primitive living, will guide parents, children and grandparents through the majestic landscapes of the Yukon, in north-western Canada. In this wilderness, untouched by human presence, discovering what life was like in prehistoric times 8,000 years ago proves to be a formidable human, physical and moral challenge. This astonishing return to our roots against the backdrop of the Yukon’s magnificent landscapes is shaped by the vagaries of the weather. Getting around, finding food, seeking shelter: adventure is a constant companion. Faced with these difficulties, the families will have to stick together and draw on new reserves of strength to get through this epic adventure with humour and perseverance.
