In a rare forest in the middle of a desert, a group of animals learned to speak and developed a big civilization to protect their "people" against the danger of the dunes. They were afraid, but were very proud of the high level of their society and used all their intelligence to build giant walls around their city. One day, a raging storm brought something mysterious to the forest. During 7 days, strange facts changed everything! O is a funny history with philosophical humor about fear (for adults and children).
