Herzblatt oder Wie sag' ich's meiner Tochter? (1969)

Widower Paul always delayed talking to his daughter about sex. But when workers on a nearby construction site are falling down their scaffold because 16 years old "Herzblatt" is tanning naked, he feels he has to take action. In the hope she'll learn herself what consequences the difference between boys and girls has, he tries to get her a boyfriend.
