A young man from an early age falls in love with a girl whose family is not in good standing with the ruling Communist party. His father however is a member of the "Stasi", the secret state police. The father not only hinders his son's relationship with the girl, but he arranges for his son, after finishing school, to become a Stasi spy himself.
