Quentin Blake's Box of Treasures S01E01 - Quentin Blake's Jack and Nancy

Adventure-loving Jack and Nancy get blown away by the wind to a tropical island. The castaways spend their days exploring this gorgeous new world, having adventures and meeting exotic creatures. But before long homesickness sets in.

Finally spotting a ship on the horizon they escape the island, returning to their own town and finally realising "there's no place like home".
