When Nazi leaders identify blonde Czechoslovakian beauty Grétka (Monika Hilmerova) as an ideal candidate to help perpetuate the Aryan race, they take her to a cryptic institution where she and other genetically "perfect" girls enjoy special treatment. But when Grétka discovers that she is little more than a breeder meant to bear racially superior children, she resists the German program. Milan Cieslar directs this drama inspired by true events.
