In the vibrant backdrop of 1970s Britain, we find Maurice Flitcroft, a dedicated crane operator employed by Vickers in Barrow-in-Furness. Living a modest yet fulfilling life, Maurice holds an inspiring belief that his sons should pursue their dreams without restraint. This belief seeds success in his step-son Michael—an ambitious figure in the Vickers yard, armed with stellar academic credentials—and also nurtures the passions of his twin sons, Gene and James, who are immersed in the world of disco dance competitions. Throughout this journey, Maurice is bolstered by the unwavering support of his ever-optimistic wife, Jean, who believes in his quirky aspirations.
However, the certainty of Maurice's life begins to waver when Michael warns him about the looming threat of nationalisation at Vickers, leading to potential job loss. Amid his uncertainties, Maurice happens to watch the British Open on television, and the lure of its generous £10,000 prize piques his interest. Encouraged by Jean, who sees the spark in her husband’s ambitions, Maurice quickly jumps into the realm of golf with naive enthusiasm, armed with a cheap set of clubs and a comically mismatched sweater vest. He dives into the sport by diligently studying an instructional book and improvising practice sessions on local beaches and fields, determined to prove his worth despite the exclusivity of the local golf club.
As the tournament draws near, Maurice finds himself baffled by the entry process. In a moment of whimsy, he decides to write to a well-known BBC golf presenter and soon discovers that all he needs is an application form. Ignoring the amateur status declaration, he boldly claims to be a professional—a ludicrous assertion that surprisingly goes unchecked by the prestigious Royal and Ancient Golf Club of St Andrews, who accept his entry without further scrutiny. During the 1976 Open, Maurice astounds the audience by recording a score of 121, marking the highest score for a "professional" in the tournament's history. His dismal performance, broadcasted live, creates a stir. It brings embarrassment to Michael, prompting concerns from his managers about family associations, yet simultaneously captivates the public, leading to an outpouring of media interest in this unconventional golfer.
The irony lies in the reaction of the R&A, who, outraged by Maurice's unintended fame and his bold declaration of returning to the tournament, banish him from competing—and even conspire to obstruct his access to all golf courses in the country. However, Maurice's spirit remains unbroken; undeterred, he immerses himself further into his golfing pursuit, adopting various aliases and disguises in his quest to re-enter the tournament, while also seeking out media opportunities to maintain his newfound limelight. Over the years, his fortunes fluctuate—although he occasionally manages respectable scores, Vickers faces mounting pressures that result in him being considered for redundancy, and Michael's estrangement from the family deepens.
Fast forward a decade, and Maurice and Jean find themselves living in a caravan, their lives starkly transformed. Gene and James have enjoyed brief fame as disco world champions, yet the decline of disco music has left them devoid of income. Returning home brings a surprising reunion, but once again their dreams are cast into doubt when Michael reproaches them for their unrealistic aspirations. Just as hopes begin to dim, Maurice receives an unexpected letter from America, heralding the creation of a unique golf tournament inspired by his infamous performances—one that celebrates playing poorly. Invited to participate as a celebrity, Maurice and his family are whisked away in first-class style, enjoying the spotlight as they are celebrated at a lavish event where Maurice is honored as the keynote speaker. Remarkably, even Michael, moved by the public's admiration for his step-father, confronts his prejudices and joins the celebration, recognizing Maurice not as a source of embarrassment, but as a beacon of resilience and inspiration.
