One Saturday morning, the Mouse brothers set out in search of adventure. The three of them were very cheerful: the oldest, the middle, and the youngest. By the edge of the path, they found a reflection, like a piece of sun. It was a tiny golden key. And with it... what could be opened? Could it be the key that will open a great treasure chest? Will it open the doors of a gigantic medieval castle? The three brothers, restless and eager to find what the key opens, will embark on an adventure to solve the great mystery. The answer, however, is closer than they think...

Sometimes we search outside and far away, losing sight of what's most important: what is within and so close to us.
