A group of hikers discover a forest. While crossing it, they learn to adapt to it and develop useful behaviors for their survival and comfort. As they go, the forest changes. From a small pine forest at first, it becomes a lush forest inhabited by numerous animals. Then, the trees become rarer, the hill steeper and the land more arid. At the end of the road, they find a precipice, which even the most experienced hiker can not avoid. What is beyond it is a mystery. Some people say there is a little pine wood.
