In a large city, where once all the nooks and crannies were filled with numerous lively mice, it suddenly became very quiet. Places that had been filled with life were left abandoned.
Only one small mouse carefully roams the town‘s alleys in search of his friends. But they are all gone, driven out by cats, birds and, above all, humans. They left in such a hurry that they had to leave everything behind and also forgot one of their own in the bustle.
Now, the little mouse is doing his utmost to follow his forlorn friends. Quickly, plans are made to reach the faraway and often longed-for land. However, all passages seem to be blocked by ferocious felines.
Only barely can our mouse escape its swift hunters as it tries to crawl onto the deck of a huge ship without being noticed. He flees through the dark channels far beneath the bustling city and meets eerie but extraordinary flying creatures lurking down there.
Lo and behold, our mouse had found a new way to reach its beloved land. The little rodent must learn to fly! Rapidly our mouse builds a flying machine using all kinds of bits and bobs it finds in the human world. But soon, we will learn that one needs more than a pair of wings to fly. As the constructions become evermore refined, the attempts at flight grow more spectacular. But these don‘t stay unnoticed for long ... Humans try to find and capture the tiny pilot, and sinister owls are not amused that their favourite appetizer is trying to conquer their realm of flight.
Times are tough for our little mouse and his big aspirations to reach a distant land.
