An hour and a quarter on an unknown planet : the Earth seen on a minute scale. The inhabitants : outlandish creatures, insects and other grass and water animals. The scenery : the impenetrable forests of grass, dew-drops as big as balloons... The film explores this new world - an ordinary meadow - over the course of a summer's day : a day, a night and a second dawn. But a single day is like a season in this minute world. A whole decade for an insect whose life-span can be counted in weeks.
