Robby

The lifeboat carrying eight-year-old Robby washes ashore on a remote tropical island. He finds no signs of other humans and realizes he must survive in isolation. The moment establishes Robby's vulnerability and the island's mystery.

Robby ventures into the island's interior, searching for signs of civilization. He finds dense jungle and empty horizons, confirming his isolation. This exploration highlights the vast, unknown world around him.

Robby falls into a lagoon and nearly drowns, but is rescued by a naked ten-year-old native boy named Friday. The two boys quickly form an unlikely friendship, despite a language barrier. Friday's lack of English heightens the sense of discovery and trust between them.

Robby abandons his clothes and he and Friday spend their days roaming the island in the nude. Robby teaches Friday English, while Friday teaches Robby to swim and navigate the waters. The pair begins a shared, clothes-free life built on play and learning.

They build a shelter and start fishing to sustain themselves, creating a rudimentary routine on the island. Their resourcefulness turns the place into a functioning home for two boys. They rely on each other for safety and companionship.

The boys confront natural dangers such as poisonous snakes and the looming threat of cannibals, hinted at by human remains they find on the island. The threats heighten the tension of their isolation and push them to stay vigilant. Their courage and cooperation are tested by the island's mysteries.

A mysterious stranger named Hank appears on the island one night, muttering to his imaginary friend Fitzgibbons. He staggers into the boys' world in a drunken stupor, waking them from their sleep. The encounter introduces an unpredictable outside element into their quiet life.

The next morning Hank wakes and investigates the area, finding Robby's t-shirt and tattered shorts on the beach. He follows the distant laughter to the lagoon and discovers Robby and Friday spearfishing in the nude. Hank's calm, nonjudgmental presence unsettles the boys and shifts the dynamic on the island.

Hank introduces himself to the boys and is treated as a guest in their naked island world. The boys share their fish and show him around, accepting his company without shame. Hank even participates in their water games, blurring the line between outsider and companion.

Hank reveals that Robby's father is connected to his work and hints at a deeper backstory. He also drops the clue that Robby's mother and father died at sea, making Robby the sole survivor. The revelation complicates Hank's role and Robby's sense of family and safety.

Hank takes Robby and Friday aboard his sailboat to return to civilization and live with Robby's wealthy aunt. The journey marks a shift from island survival to urban life, with new adults and expectations awaiting them. The departure foreshadows the tensions that may arise in their new world.

Back in civilization, Robby and Friday listen to a seashell that reminds them of the ocean and their island adventures. They recall running naked on the beach and skinny-dipping with nostalgic warmth. The seashell becomes a tangible link between their island life and their present world.
