Anna and Benjamin live in the city but love to stay with their cousin Robin in the countryside. Robin takes the children to see his favorite tree in the nearby forest: a 300-year-old giant oak.
Each time the children visit, they are amazed at how the forest and the mighty oak changes with the seasons. In autumn, they build a cosy den in the tree's roots to watch the squirrels. In winter, they learn to ski in the shelter of the forest. In spring, they search the forest for animals. But some creatures can be dangerous, and one night, the old oak tree helps Benjamin when he discovers something he wasn't expecting. . .
Join Anna and Benjamin as they spend the seasons with the great oak tree, and discover the fascinating plants and animals that live around it.
