Niko cannot begin to imagine the consequences of following the path that intersects the road he takes each day to get to school. Attracted by a mysterious house that he has never noticed before, he enters and is immediately immersed in a strange universe. Within the quantum world, strange, amazing things occur, from a war between matter and antimatter to the disappearance of Schrödinger's cat. Niko’s mission is to restore the balance, now endangered, between his world and the quantum universe that he has just discovered.
