The little sapling emerges from the ground excited to one day become a big, tall oak tree. However, it soon discovers that growing is not easy as it faces threats from humans and the changing seasons. Through facing winter, losing leaves to the wind, and having branches eaten by deer, the sapling grows stronger each year with the help of the sun. After a century, the oak tree has lived a long, beautiful life providing shelter and food for animals and protection to other plants.
