New Europe presidential candidate Etienne Alexis is a scientist promoting artificial insemination for social betterment and therapy to eliminate passion. To celebrate his engagement to a cousin, he hosts an aseptic picnic, where Mother Nature asserts herself. A shepherd's flute conjures a windstorm throwing Alexis together with the luscious Nénette, a farm lass who, although unimpressed with men, wants to have a baby.
