A husband who barks also bites

When 16-year-old Sonja becomes pregnant, it turns her life upside down. Her parents are ashamed of her decline, so they take her to an aunt in another town and force her to give the child up for adoption. Sonja will never forgive them. On her eighteenth birthday, she marries the much older Hynek, who offers her a comfortable life in a golden cage - with one condition: never any child. Sonja takes the loss of her daughter badly and would not even think of replacing her with another child. She likes Hynek and lives with him quite happily until a stranger rings the doorbell of her luxurious villa and introduces herself: I'm your daughter's mother.
