Nikola Tesla sits in a hotel room in 1943, talking with a reporter and imagining how history might have unfolded if J.P. Morgan had listened to him. The scene soon unfolds into a longer memory, tracing a life shaped by ambition, risk, and a relentless belief in a wired and unbound future.
The story moves back to the 1880s, when Tesla arrives in the United States with a radical idea: an electric induction motor powered by alternating current. He seeks backing from a new employer, Thomas Alva Edison, only to be rebuffed—Edison insists that direct current is superior and practical, and he dismisses Tesla’s invention. After the disappointment, Tesla finds himself digging a ditch, having left Edison behind. Amid this tension, Robert Underwood Johnson and his wife, Catherine Johnson, attend the early demonstrations and witness how the world of science and business can shift on a single moment of perception.
With determination, Tesla secures funding from two investors to push the motor forward. He demonstrates the AC system at a meeting of the American Institute of Electrical Engineers, while Edison remains skeptical and public sentiment teeters on the edge of disbelief. The balance of power shifts when George Westinghouse steps in, recognizing the potential and agreeing to buy Tesla’s AC patents, offering a royalty contract that promises ongoing support for the inventor’s work. The collaboration between Tesla and Westinghouse becomes a race against time and competing interests, with Edison opposing the trend toward alternating current as a safer, more efficient alternative to DC.
Behind the scenes, J.P. Morgan pulls the strings, arranging meetings that test the viability of AC in Morgan’s vast network. He challenges Tesla to prove that alternating current can power industry on a grand scale, and he also questions Edison’s stance as the public struggle to separate hype from reality intensifies. The tension culminates in a banquet celebrating a new AC-powered plant at Niagara Falls, where Tesla shares visions of a high-frequency, wireless transmission system that could reach far beyond conventional grids. Before long, a European trip beckons Tesla, who plans to see his family as he wrestles with personal losses—the memory of his bed-ridden mother returning to him in flashes of water and lightning.
Back in the laboratory, Westinghouse and Catherine Johnson visit Tesla, who makes a bold, symbolic gesture by tearing up his royalty contract in an act meant to save Westinghouse from financial ruin and keep the collaboration alive. Tesla presses forward with his wireless power project, sending progress reports that Morgan reviews with a careful, if wary, eye. The financier admits concern about the sensational stories surrounding the inventor, yet he continues to back the venture for a time, balancing risk with the possibility of a breakthrough.
As the Wardenclyffe project—Tesla’s grand experimental station—nears completion, new challenges loom. Tesla discovers that Guglielmo Marconi has appropriated his wireless patents, while Einstein’s emerging theories about matter and energy complicate the scientific landscape. Tesla deems these developments a “crime against nature” and pleads for Morgan to sustain a truly free wireless power system before it is too late. Yet Morgan withdraws his support, choosing to protect his broader financial interests over the inventor’s bold, untested vision.
In his final reflections, Tesla surveys a world increasingly choked by smog and finds himself wondering what might have happened if Morgan had listened to him. The dream of frictionless wireless power remains unfulfilled, and the film closes on a note of quiet lament—an emblem of what could have been if the future had been allowed to unfold on Tesla’s terms.
