A not-so-young doctor tries to explain to women of the fifties (in a small village in the mountains) that painless childbirth is possible, and that the old curses -coming from long ago and far away, check the Genesis - must go. He will meet with macho men, but also submissive women - who will be his strongest enemies -, who still think that "the more you suffer, the more you love your baby". To fight such drivel, doctor Laurent expresses himself in astute images. What is obvious today was a big revolution then.
