The world is turned upside down when an entire large building disappears without a trace overnight. It was the school building of three girls: Annabell, Lara, and Maya. What no one knew at the time was that, to escape its fate, the sensitive school building had decided to transform itself into a human being, a young woman. She takes her first steps in her new body into a new mobile life. Unable to believe what this new body demanded of her, she fell into a disastrous spiral. The three girls, their seer Sven, and his dog Timmy must find the woman at all costs to end the further chaos her disappearance has caused. But the search for their school building takes the girls on an even greater adventure. It will exceed their imaginations and expectations by a cosmic dimension. Like in a labyrinth, new tasks, conditions, and rules unfold again and again, which they must learn, endure, and master. As Ba birds, they will rediscover the world for themselves - as birds see it. This helps them to track down the magnetic field lines. These are clever, capricious, and tricky forces of nature that want to do good, but also play their own game and skillfully entangle the three girls in it. When they get stuck, it helps to turn their own helplessness into the curiosity of others. The three girls had to learn this the hard way before they tried it themselves.
