In the mists of the Swedish Taiga, near Tackåsen, a team of doctors and scientists are on the tracks of brown bears, following them into their den. They’ve got an incredible mission: taking blood and tissue samples and carrying out a whole host of medical tests on hibernating bears. Their aim? To understand the exceptional resistance these plantigrades have, in order to find a cure for common human health issues. Today, osteoporosis, muscular atrophy, obesity, cardiac and renal deficiency are rife in society. Does the physiology of bears hold unknown therapeutic solutions to these modern-day illnesses? This documentary recounts their journey in breath-taking, never before seen sequences: tracking the bears by helicopter, discovering their dens and removing the animals, 3D scanning and cardiac ultrasounds on sleeping bears in the wild. Other sequences show research in prestigious institutions through cutting edge equipment, with animals being treated with great care and respect by professionals. Will the bear put science on the tracks of new treatments for illnesses of today’s society?
