Abraham Lincoln, Raymond Massey, leaves home for the first time when he's hired along with two friends by Denton Offutt to haul a load of pigs by water to New Orleans. The journey starts as a practical job, but trouble arises when the boat stalls at a dam near the settlement of New Salem, and Lincoln’s heart is drawn to Ann Rutledge, Mary Howard, the tavern keeper's daughter. This sudden romance becomes the compass of his early years, even as he takes up a position at Offutt's store in New Salem and begins to navigate a world that values wit, nerve, and the chance to rise.
Abe quickly learns that Ann already has a beau, yet his easy humor and unassuming charm soon make him the most popular man in town. He also seeks to improve himself by learning from the patient, perceptive schoolteacher Mentor Graham, [Louis Jean Heydt]. When Ann’s would‑be fiancé leaves town to better himself, she waits for him for two long years. A letter arrives saying the man cannot say when—or if—he will return, and Abe seizes the moment to profess his love. Ann is cautious about giving her heart, asking for time to sort out her feelings. The two share a tentative, hopeful bond, tempered by uncertainty and the weight of social expectations.
Tragedy soon shadows their growing intimacy. Ann dies of what the era calls “brain fever,” and on her deathbed she admits that she could have loved him. Her loss deepens Abe’s sense of purpose and nudges him toward public life. He is urged to run for the Illinois General Assembly and wins, launching a political path that will carry him from the little towns to the heart of the nation. After a first term in Springfield, Lincoln decides to study law, hoping to sharpen his capacity for leadership and service.
Mary Todd Lincoln, [Ruth Gordon], visits her sister Elizabeth Edwards, [Dorothy Tree], and their husband, the influential Ninian Edwards, [Harvey Stephens], at a social gathering where many eligible men are present. Among the attendees is Stephen Douglas, [Gene Lockhart], Lincoln’s charismatic rival in the political arena. Yet it is the plainspoken, unpolished Abe who captures Mary’s attention. She glimpses in him a potential greatness that she believes must be cultivated, and she resolves to steer him toward the destiny she envisions for him, even if his own ambition is initially modest. The social whirl becomes the crucible in which their alliance is formed, shaping not only their personal lives but also the arc of the nation.
Abe proposes marriage, but he wrestles with hesitation; after a period of doubt, he steps forward again, and Mary accepts. Their partnership deepens as years pass and they raise a family that includes several children—each new life reinforcing Lincoln’s commitment to a higher calling. The couple’s private joys and public duties begin to blend, forging a bond that will endure through the most demanding chapters of American history.
As Lincoln’s reputation grows, he runs for a seat in the U.S. Senate and engages in a grueling series of debates with Stephen Douglas, [Gene Lockhart], where the central issue—slavery—becomes the crucible of his political philosophy. In a moment that would become emblematic of his career, Lincoln speaks with quiet authority about the morally combustible reality of a nation divided. The exchange culminates in a defining line that would echo through the ages: > "A house divided against itself cannot stand."
With the presidential election looming, the party is so fractured that the frontrunners are unacceptable to many factions. In a late-breaking turn of events, the leaders settle on Lincoln as a dark-horse candidate, recognizing in him a unifying figure capable of moving the country toward a new dawn. He wins the nomination and, after bidding farewell to friends and supporters, boards the train to Washington, D.C., prepared to confront the immense challenges that lie ahead.
The story that unfolds is one of quiet determination and humane rigor, tracing not only the ascent of a man who would become one of history’s defining presidents but also the personal choices, losses, and relationships that help shape his resolve. It honors the humanity behind the legend—the humor that endears him to a small town, the intellect that sharpens his convictions, and the moral clarity that would anchor a nation during its most turbulent era.
