In St Andrews, Scotland in 1866, 15-year-old Tommy Morris (Jack Lowden) is an avid golfer like his legendary and pioneering father, Tom Morris (Peter Mullan). “Old Tom” is a greens-keeper for The Royal and Ancient Golf Club of St Andrews, as well as the town’s club- and ball-maker. He is the two-time winner of the first major golf tournament, The Open Championship, which he founded in 1860. He also established golf’s standard of 18 holes per round. But young Tommy is beginning to chafe at his father’s dictates, especially in the rapidly changing world they live in.
Tommy soon outshines his father, winning The Open three times in a row while still in his teens. The “dashing young man of golf”, he draws flocks of spectators to the sport and becomes it’s first touring professional.
Father and son repeatedly clash over the unwritten rules of social class, and this culminates when Tommy marries his sweetheart Meg (Ophelia Lovibond), a woman of lower standing with a shameful secret in her past. As the story concludes, Old Tom makes a fatal misjudgment that strips Tommy of everything he holds dear. Following the results of that fateful choice, Old Tom takes on a personal mission that carries him through the final decades of his life: that of honoring his son Tommy
