While Ma is drawing, Mi finds himself blocked by a large stone in the middle of the path. All alone, he can't push it and he is unhappy to be stuck. Ma explains to him that two people can change the world; the big stone is then transformed into a happy slide.

Mi and Ma try to capture a leaf that is dancing above their noses. But nothing can be done, the leaf plays with them and does as it pleases. The two children will gradually understand that the leaf is as free as the wind and that it chooses to be caught or not.
