Priests who call sex education the devil's invention rage against the progressive doctor whose bigoted wife may regret when his teenage daughter comes home and wants an abortion.

The model for Doctor Borg was the well-known Katrineholms lecturer Torsten Wickbom, who advocated modern sexual education in the school and family.
