Nothing ever happens on Kasia's street. And Kasia would know, because her illness makes her spend days stuck at home, watching the world from her bedroom window. So when she sees what looks like a kidnapping, she's not sure whether she can believe her own eyes... There was a girl in the window across the street-did she see something too? But when Kasia goes to find her she is told the most shocking thing of all. There is no girl.
