The bears set off from the mountains to the city in search of their ruler's lost son. People are getting ready to fight against, in their opinion, dangerous beasts. Are these two worlds compatible with each other?

A wandering storyteller and his little assistant meet an old bear in a cave. They tell him the story of the famous invasion of Sicily by his brothers. And it was like this: a herd of bears, under the leadership of their king, set out in search of the king's son who had been kidnapped by men. Animals found their way to a human land that is not friendly to them. The film is a colorful and fanciful animation about identity, noticed e.g. at the Cannes festival, where it premiered.
