Set in 1921, the story follows British inventor William Friese-Greene, Robert Donat as he wrestles with severe financial distress while attending a London film industry conference that will be told largely through a tapestry of flashbacks. The narrative initially centers on Helena Friese-Greene, Maria Schell, who recounts how she first met Willie, their marriage, and the four sons they had amid a growing, relentless pressure from his obsession with color film. The strain takes a toll on the family: their three eldest boys even lie about their ages to enlist in the army during the First World War, and Helena ultimately leaves him, unable to endure the mounting tension.
Back in 1921, Friese-Greene is deeply discouraged by the conference attendees, who seem absorbed by the commercial side of filmmaking rather than its artistry or science. When he attempts to speak, he is dismissed and ignored, a moment that sends him spiraling into a longer flashback about his early career.
In this extended recollection, Willie begins as an assistant to the photographer Maurice Guttenberg, a man who resists giving him creative freedom. After a disagreement over portrait techniques, Willie leaves to strike out on his own with his new wife Edith, Margaret Johnston, a former client. Although they start with several studios and a modest early success, Willie’s ambitions increasingly tilt toward moving pictures and the development of color processes—often at the expense of his profitable photography work. He even abandons his wife at a choir concert to pursue a meeting with the photographic pioneer Basil Sydney, who embodies the legend of Fox Talbot, and returns home buoyed by the encounter.
Willie relocates to London and teams up with the businessman Arthur Collings, Eric Portman, to push his film experiments forward. Collings initially offers support, but the mounting financial burden strains the partnership to the breaking point, forcing Willie to mortgage his home to raise more funds. A Sunday excursion in Hyde Park becomes a turning point when he films relatives with his new camera, and that very night he develops the footage, watching light dance across the frames with a sense of breakthrough and wonder.
Despite his optimism and the belief that they are on the cusp of wealth, bankruptcy soon follows. Helena, exhausted by the endless cycle of risk and disappointment, collapses in a side office at the court. A doctor prescribes a year of rest, but she privately tears up the expensive prescription while returning home and sells her jewelry to fund a new studio for her husband. On his birthday—forgotten by him—she gives him a prism, a small symbol of hope that she hopes will rekindle their collaboration.
Back at the 1921 conference, Friese-Greene rises once more, clutching film reels as he speaks about a new era in cinema. In a defiant and impassioned moment, he proclaims cinema to be a “universal language,” a line that is echoed by a doctor who arrives too late to save him from collapse. The scene ends with the doctor finding only enough money in his pockets to purchase a cinema ticket, a bittersweet reminder of the dream that his life had represented.
This biographical arc blends intimate domestic struggles with the stubborn, high-stakes pursuit of technological progress, painting a portrait of a man driven by vision even as his personal life frays around the edges. The film uses Helena’s perspective to ground the narrative in emotional reality, while Willie’s intense pursuit of color technology traces the early, formative era of moving pictures. Thematic threads of devotion, sacrifice, and the price of obsession run through both the family drama and the scientific quest, culminating in a poignant meditation on the cost of chasing a dream that changed the world of cinema.
