Benjamin and Anna love staying with their cousin Robin in his house near the forest. In the autumn, Robin takes them to see his favourite tree - a giant oak which is 300-years-old. The children build a den under the oak tree's giant branches and watch the squirrels hide acorns in its wide trunk. In the winter they ski through the forest and meet the foresters who chose which trees will become firewood this year - but not their beautiful oak tree! In the spring the children go searching for the animals that live in the forest - snuffling badgers, gentle deer and shy rabbits. One night, the tree helps Benjamin when he discovers a creature he didn't expect. How can the children say thank you? --
