Niki Lukasser's father has walled Dr. Weiss into the barn loft. His box is one meter wide, three meters high, and four meters long. Hiding Dr. Weiss seems like an adventure to Niki. At first. But the family's secret weighs on them. Mrs. Lukasser becomes "nervous." Mr. Lukasser withdraws. Care and feeding of Dr. Weiss fall to Niki and a blind girl - Niki's best friend, Sigi.

Niki and Sigi straddle two worlds. In their adolescent world, they are discovering the limits of adult life, and the possibilities of each other. In the secret world they share with Dr. Weiss, they have power - a life depends on them. That is both gratifying and bewildering.

As the psychological state of Dr. Weiss ebbs and flows, Niki and Sigi are entranced by the stories of his worldly life in a Europe very different from their own. He shows them how to dream beyond their village, beyond the war. They are beginning to understand compassion and respect. And from the inside of his box, Dr. Weiss is gradually coaxing them into adulthood.
