In the year 1868, unsettling rumors about a terrifying sea monster wreaking havoc on ships in the Pacific Ocean stir a sense of dread and panic among sailors, severely disrupting vital shipping routes. In response, the United States government reaches out to Professor Pierre M. Aronnax and his resourceful assistant, Conseil, inviting them to join an exciting expedition aiming to ascertain the reality of the rumored beast. Ned Land, a brash and confident master harpooner played by Kirk Douglas, joins their ranks, infusing the journey with his bold bravado.
After months of arduous searching across the unforgiving ocean, they finally sight the rumored “monster.” A fierce confrontation ensues, and despite the ship’s crew firing cannons in a desperate attempt to fend it off, the beast violently lunges, ramming their vessel. In the chaos, Ned and Aronnax are unceremoniously thrown overboard, with Conseil quickly plunging in to rescue Aronnax. Adrift in the merciless sea, the three castaways culminate their ordeal by stumbling upon an odd, metallic vessel that turns out to be a man-made “submerging boat.” To their astonishment, it appears deserted.
Within the vessel’s confines, Aronnax discovers a viewing window through which he witnesses an eerie underwater funeral, hinting at the dark and unexpected mysteries within the depths. Shortly after, the submarine’s crew returns, capturing the trio, and their enigmatic captain Nemo, to be portrayed by James Mason, introduces himself as the master of the Nautilus. While he promptly returns Ned and Conseil back to the deck, he extends an intriguing offer to Aronnax, acknowledging his notable research and achievements, tempting him to stay aboard the vessel. Convinced that his companions would perish without him, Nemo ultimately allows Ned and Conseil to rejoin the submarine.
In a series of breathtaking underwater adventures, Nemo unveils his unique way of life beneath the waves. From a specially crafted seafood menu to his underwater hunting grounds, each revelation paints a portrait of an extraordinary existence. Interestingly, Ned realizes that Nemo’s crew leaves treasures undisturbed as they find them, leading to a pivotal moment when Nemo informs him that he has no need for gold or jewels; rather, a “sound mind and a full belly” bear far greater value. While Aronnax yearns to unveil the secrets of the ocean through the opportunities presented by Nemo, Ned remains fixated on the allure of treasure and the chance of escape.
The plot thickens as Nemo takes Aronnax to visit the penal colony island of Rura Penthe, revealing his own tortured past as a prisoner, much like many of his crew members. In a shocking turn of events, surrounded by the oppressive ambiance of captives loading a munitions ship, the Nautilus charges and decisively destroys the vessel, sparking a damaging explosion and resulting in the loss of countless lives. An anguished Nemo confesses to Aronnax that his brutal actions were designed to save thousands from the ravages of war, recounting the torment inflicted upon his wife and child by the very nation responsible for his imprisonment, which manipulated him to disclose the secrets behind his groundbreaking innovations, such as the submarine technology and a powerful yet enigmatic energy source, hinted to be nuclear.
As tensions rise, Ned uncovers coordinates marking Nemo’s clandestine island base, Vulcania, and desperately attempts to send out messages in bottles, hoping for a chance of rescue. However, disaster strikes when the Nautilus becomes trapped on a treacherous reef off the coast of New Guinea. Surprisingly, Nemo permits Ned to go ashore with Conseil under the pretext of obtaining specimens. Nonetheless, driven by the instinct of self-preservation, Ned ventures off alone in search of an escape route and stumbles upon grim trophies of human skulls on stakes. Realizing the imminent threat of cannibals, he dashes back, seeking refuge along with Conseil, just as they inadvertently draw the ire of the island’s savage inhabitants.
Despite the imminent danger, Nemo appears unfazed, and the cannibals are ultimately thwarted from boarding the Nautilus due to electrical defenses. In a moment of intense frustration, Nemo confines Ned to the submarine’s brig for disobeying his orders. The narrative escalates further when a warship approaches and starts firing upon the submarine, forcing it to plunge into the depths where they cross paths with a colossal squid. As the vessel struggles against the monstrous creature, a dramatic twist unfolds: Nemo becomes ensnared within one of the squid’s writhing tentacles. In a moment of heroic reckoning, Ned escapes his confinement and leaps into action, rescuing Nemo from certain doom, prompting a shift in Nemo’s perspective as he expresses a newfound desire for peace with the surface world.
As they approach Vulcania, Nemo confronts the formidable presence of warships that threaten his sanctuary. In this critical moment, as Ned seeks to identify himself as the sender of the bottled messages, Aronnax’s heart races with anger and desperation, foreseeing doom for both them and Nemo’s pioneering discoveries. Tragedy strikes when Nemo, mortally wounded from a gunshot, sets a bomb in his hideout, resolute in his final act of defiance against his pursuers. With grim determination, he navigates the Nautilus away from Vulcania, declaring he will “take the Nautilus down for the last time.”
As his crew collectively resolves to accompany their captain into the depths, Aronnax, Conseil, and Ned find themselves locked away in their quarters at Nemo’s command, while the submarine’s crew retreats to their cabins. Unyielding, Ned breaks free and manages to resurface the Nautilus, albeit crashing onto a reef in the process and causing an impending flood. In a heart-wrenching moment, Nemo approaches a viewing window, filled with melancholy as he watches the beloved ocean—a final farewell to the life he cherished. In a race against time, Aronnax makes a desperate attempt to recover his journal, chronicling their unforgettable voyage. However, urgency forces Ned to knock him unconscious and carry him to safety. The companions witness an explosive demise as Vulcania is engulfed in flames, and as the Nautilus submerges into the depths, Aronnax is haunted by Nemo’s haunting last words:
“There is hope for the future. And when the world is ready for a new and better life, all this will someday come to pass, in God’s good time.”
