The cheerful and mischievous siblings Nicke and Nilla hang out in an old attic where anything can happen and anyone can show up. Nicke is a boy who thinks he knows and can do everything better than everyone else. He likes to flirt with girls but most of all he loves reading The Phantom. Nilla is a fearless and lively girl who wants to be in charge. The siblings always stand up for children, solve problems, and set things right. Maybe not always in the way you would expect. But they take difficulties and problems, big and small, very seriously and solve things in their own inventive way.
