Soon after the Thompson family’s arrival in the countryside, the three children – Joe, Beth, and Fran – discover a magical tree and its extraordinary and eccentric residents, including Moonface, Silky, Dame Washalot, and Saucepan Man. At the top of the tree, they're transported to spectacular and fantastical lands and, through the joys and challenges of their adventures, the Thompsons learn to reconnect and value each other for the first time in years.
