Read the complete plot summary and ending explained for Robby (1968). From turning points to emotional moments, uncover what really happened and why it matters.
On a remote tropical island, a lifeboat washes ashore, carrying eight-year-old Robby who begins a quiet, solitary awakening to a world far from adults or rules. He moves along the shore, curious and cautious, until he discovers there are no other people on the island. A perilous moment in a lagoon almost ends in tragedy, but Robby is saved by a naked ten-year-old native boy, whom he befriends and names Friday. The moment marks the beginning of an unlikely companionship rooted in survival, trust, and a shared sense of innocence in a place where adults are absent.
As days turn into routines, Robby sheds his clothes and the two boys roam freely, their bond growing stronger as they navigate the island together. Robby teaches Friday how to speak English, gradually turning their conversations into a bridge between two different worlds. In return, Friday teaches Robby to swim, and the two celebrate a first, carefree plunge into the sea as they discover the exhilaration and fear that come with skinny-dipping and being exposed to the open water. Robby fashions a simple pair of jean shorts for Friday from his shirt, a small act that becomes a symbol of their growing trust and shared ingenuity. Life on the island becomes a joint project: they build a shelter, gather food, and learn to read the rhythms of the land—the patterns of the tide, the signs of fish, and the quiet dangers that lurk in the underbrush.
Their island existence is not without peril. They encounter poisonous snakes and stumble upon disturbing signs of cannibals—evidence that hints at danger beyond the natural world. The mood shifts with a sudden, unsettling presence: a stranger arrives one night, breaking the rhythm of their days with a mix of mystery and unpredictability. The stranger, who introduces himself as Hank, rouses Robby and Friday from their sleep with a drunken urgency, muttering to an imaginary friend named Fitzgibbons. The boys wake to a scene that feels both surreal and intimate, as they stand in their natural state, unencumbered by clothing, while Hank looms in their shared space. The moment forces them to confront the fragility of their shelter and the precariousness of even this hard-won safety.
The next morning, Hank awakens to the island’s sounds and follows them as they roam the beach and lagoon, now more curious than cautious about their guest. He notices Robby’s tattered t-shirt and shorts left behind near the hut, and hears laughter that seems to come from nowhere. His search leads him to the lagoon, where he discovers Robby and Friday fishing in the nude, a scene that underscores how unguarded their world has become. Hank introduces himself to the two boys, and they respond with a cautious openness, sharing their catch and showing him the lay of the land. The trio’s dynamic is unusual but nonthreatening: the boys do not feel the need to clothe themselves around Hank, and Hank does not admonish them for their nakedness; instead, he participates, even joining them in a dip in the warm ocean.
As the days pass, Robby asks Hank about his knowledge of Robby’s father. Hank answers with evasive honesty, saying he does not know him, yet hints that he is familiar with the father’s work. There is a sense that Hank is hiding something, a thread that invites Robby to pull at it but also warns him of potential danger. The revelation soon deepens: Hank explains that he learned of Robby from a newspaper article indicating that Robby’s mother and father died at sea, leaving Robby as the sole survivor of the shipwreck. This confession shifts the boys’ bond from one of companionship to one of kinship, with Hank becoming a kind of guardian figure who has navigated the edges of danger and loss.
Hank eventually decides to bring Robby and Friday back into civilization, guiding them aboard his sailboat to live with Robby’s wealthy aunt. The journey from the island back to the world of port towns, stores, and social expectations marks a transition from the raw, sun-soaked simplicity of survival to the more complex realities of family, memory, and legitimacy. The soundtrack of their escape is woven with the memory of the sea: even after they return to land, Robby and Friday find solace in a seashell’s echo of the ocean, a reminder of the island’s quiet, endless horizon.
Back in civilization, the two boys hold on to the intangible sweetness of their time together. The seashell becomes a symbol of what they shared: the freedom of running along a shoreline, the days when they played Cowboys and Indians with the shoreline as their boundary, and the fearless thrill of skinny-dipping in saltwater spray. The film closes on a note that balances nostalgia with the stark honesty of memory: a boy who survived a shipwreck and a friend who learned a new language and a different way of moving through the world now carry those lessons with them, tempered by the knowledge that life can be both simple and complicated, exhilarating and fragile, all at once.

On a remote tropical island where the ocean’s rhythm becomes a silent ruler, an eight‑year‑old castaway awakens to a world untouched by adult rules. The sun‑bleached shore, the whisper of palms, and the ever‑present tide craft a landscape that feels both timeless and intimate, inviting a child’s imagination to fill the empty spaces.
