Surviving shipwreck, the Robinson family finds that life on a bountiful deserted island is filled with adventures, dangers, and family fun. Each episode of this classic adventure brings a lesson of hope, joy, and the value of a strong and loving family.
When ammunition for the rifles run short, the Robinsons fashion bows and arrows, and Becca amazes everyone with her skill. Sap from rubber trees provides new shoes for the whole family.
The children surprise their parents with a concert and a vacation cottage to celebrate their wedding anniversary. But the 'second honeymoon' takes a strange turn when jackals attack, and they scare them off by setting the cottage on fire.
Jack is stricken with malaria, and his father begins a desperate search for cinchona bark to treat the deadly disease. Mother falls ill, and it is a race against time for the whole family.
Becca would rather explore the island than study, and sneaks off for a walk in the forest. She is soon hopelessly lost, and the family is thrown into turmoil.
Becca is punished for wandering off, but the next day leaves her chores again, this time to round up the family's frightened goats. Becca returns expecting punishment but finds understanding.
The Robinsons plan a birthday surprise for Becca, but all the secrets make her feel excluded and she sulks. When the party and presents are revealed, she learns to her delight that things are not always what they seem.
Fritz and his father construct a boat, while Mother preserves food for a long voyage. The ship's trial run is a success, but during the night a violent storm destroys the ship and crushes the family's hopes for escape.
The storm that crushed the Robinson's boat continues, and the rain disrupts their activities. But it also brings some surprising benefits, the floods wash fish and fruit into easy reach and inspire new indoor fun.
The tree house roof gives way under the constant rain, and the Robinson's search for a new home. Becca remembers a cave, found when she was lost in the forest.
The cave is dry, but is it hospitable? The Robinsons find the cave already occupied by multitudes of bats, and a skeleton, the grim remains of an earlier shipwreck victim who once lived on the island.
