A children's program where we meet the two cheerful and mischievous brothers Nicke and Mojje who hang out in an old attic where anything can happen and anyone can show up. The brothers 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 ways. Music and singing are something the brothers enjoy, they write their own clever lyrics and play, among other things, guitar and harmonica.
