This is the World Masterpiece Theater trick at full strength: fifty episodes that make you care about building a roof, hauling water, and getting through one more season without anybody getting sick. Nippon Animation took Wyss's old castaway novel and handed it to Flone, a ten-year-old from Bern who climbs everything and refuses to be the daughter who waits on shore, and the whole show is better for it. The setup is unglamorous on purpose. A doctor gets a letter begging him to come to Australia because there aren't enough doctors, the family packs up a comfortable life in Switzerland, and the ocean does what the ocean does. What sticks isn't the shipwreck, it's the domestic arithmetic afterward, the salvaged supplies, the improvised shelter, a father still practicing medicine with nothing. You finish it strangely homesick for a place with no walls."
A family uproots from Switzerland bound for Australia, seeking a fresh start after receiving an urgent call for medical help. When their ship encounters a violent storm, the Robinsons find themselves stranded on an uncharted island with nothing but their wits and determination to survive. Flone, an adventurous ten-year-old girl, becomes the heart of this family's new life. While her father struggles to establish a medical practice and her mother tends to household needs, Flone throws herself into exploring the island's mysteries and resources. She discovers hidden waterfalls, befriends local wildlife, and uncovers secrets the island holds. Her courage inspires her siblings and parents to embrace their circumstances rather than despair over them. The series balances survival challenges with quieter moments of discovery and growth. As seasons change and dangers emerge, the family learns what truly matters: their bond with each other and their connection to the natural world around them. Flone's journey transforms her from a restless girl into someone who understands resilience, responsibility, and wonder in equal measure. Each episode reveals how ordinary people find extraordinary meaning when stripped down to basics and forced to reimagine home.
