Daan Stigter

Young Peter has a difficult time adjusting at school having been confined to a wheelchair after an accident. He still wants to participate in the school outing and play and wants to come up with a way to make the play actors 'fly' like fairies. By chance the local inventor Quirinus Drijfhout and his son Felix have just perfected their 'Zerostraler', a machine that can make any object float in mid air.

Three children and their uncle find a magic painting in the uncle's attic. When they pronounce a spell, a lady named Esmeralda emerges from the painting. The lady must return to the painting, unless certain conditions are fulfilled. A magic drink, which makes them invisible, should help them. Two thieves (who seem to like nothing but cakes) kidnap one of the children to require a ransom. And it is found that a man, the father of Peter Faber (that's the name of an actor too, but not in this movie) is needed for help. That is not easy, since the they are not on friendly terms with Peter and his father.
