The film is inspired by an incredible story of a shepherd dog named Palm who was inadvertently left in the airport by her owner. She befriends nine-year old Nicholas whose mother dies leaving him with a father he barely knows - a pilot who finds the dog at the airport. It's a story of amazing adventures, true friendship and unconditional love.

After leaving commercial aviation, Vyacheslav Lazarev and his family move to the countryside, where he continues to go flying, but now on a small propellered AN-2. And the life of the Lazarev family goes on as usual, until one day a small bear cub, to whom Kolya, the pilot’s son, gives the nickname Mansur, bursts in. When Mansur is kidnapped by local poachers, the faithful sheepdog Palma comes to his aid. The two animals need to find their way home through a forest full of wild animals, hunters and other dangers. And the Lazarevs, who set off in search of their four-legged friends, will have to remember what it means to be a real family.
