British naturalist Sean Ellis devoted his life to a strange and difficult task: to reconcile two predators that have been at war since ancient times - man and wolf. The ultimate goal of his research is the restoration of the number of wolves in the wild, which, according to his theory, will lead to the flourishing of flora and fauna, and in the long term, the healing of our damaged planet. But what path does he take to achieve this goal? Practitioner Ellis shocks theoretical biologists by communicating with wolves as equals and completely sharing their way of life. Is it a joke to go to the mountains, find wild wolves and live with them for almost two years as an equal member of the pack? Eat and sleep like them, growl and fight, howl at night, participate in raising puppies? For Ellis, all this is still quite an ordinary pastime. The story of his life is more fascinating than any novel: dizzying adventures that no one alive today has known, amazing discoveries and something new - or very ancient? - a way of looking at the world around us.
