This film is a tribute to a humiliated and destroyed nation. "As Long as the Grass Grows" is an alternative, ancient and humble creation story, where man is not the crown of the creation, but the weakest of all creatures. The film takes us back to the beginning of time, where Old Man begins to create the world out of a handful of mud. Everything he creates is new and nameless, and affects the rest of the world. Even feelings and desires are unknown and when they emerge, the world becomes more and more complicated.

The green Verdies are the tiny, but brave guardians of the lakeside. The young Verdies only become guardians when their hair turns brown. Until then, however, life is boring. The youngsters with green hair are not allowed to fly on warblers, not allowed to row alone, and they're not allowed to ride wild frogs at the rodeo. Willy Whistle's big dream is to become a guardian, but his curiosity always gets him into trouble. However, the whole lake becomes at risk when the enemies of the lakeside, the Grimps and the swans, enter into alliance. The guardians are helpless, but Willy comes up with a daring plan in order to save his home and his trapped friend, Jeremiah Jump. Luckily he is not alone, because Grandpa, the water snakes and the frogs also come to his aid.
