Op een mooie zomerochtend dalen de biologen Claude Nuridsany en Marie Perennou af in de jungle van een grasveld. Ze gaan er op zoek naar de bewoners van een onbekende wereld binnen de wereld, die van de fantastische wezens die tussen het gras en op het water leven.
Nee, helaas is Microcosmos nog niet beschikbaar op Netflix in Nederland.
