The "Concordia" trading company in Würzburg is a secret headquarters of the MID, a secret service agency of the US Army. For years, espionage, sabotage, and diversion operations originated from here in order to undermine the Socialist Republic of Germany. A favorable moment for a military attack approaches and plans are developed. These plans are placed in the hands of Major Collins, who keeps them in a safe. Hansen has worked for him for many years, but also for the Stasi as a double agent. Security Chief Colonel Rock knows there is a leak, but Hansen has passed every test thrown at him. He is trying to deal with his current assignment: acquiring the plans so they can be made public. His mission is to get them out of the safe and into the GDR without getting caught.

After World War II, scores of refugees leave in search of a new home. They now stand in the hall of a large mansion, waiting to receive their deeds of ownership for sections of land that the lord of the manor had left behind after he fled. Among them is young Jeruscheit who, during her travels, had to bury one of her own children. Her husband has been declared missing, and up until now she has had little purpose in life. But then she discovers it: to work, to build, and to help others. And maybe someday Jeruscheit will find her family.

Two young building workers are more interested in girls than their work; complications ensue at home.
