George Morton, a young man from a ruined family, finds his life upended when he meets Sylvia Planter, the haughty daughter of a wealthy estate owner. After a passionate and humiliating encounter where he confesses his forbidden adoration, Sylvia has him dismissed as a common servant. Stung by her contempt, George vows to transform himself into a man of equal standing, education, and power. He leaves for Princeton University, where his athletic prowess on the football gridiron and his fierce intellect under the tutelage of the eccentric tutor Squibs Bailly pave his way into the elite social circles.
At college, George navigates the treacherous waters of undergraduate politics and social snobbery while fiercely guarding his secret past. Despite forging deep friendships and catching the eye of the kind-hearted Betty Alston, George remains single-mindedly fixated on his ultimate goal: to conquer his social inferiority and make Sylvia acknowledge him as an equal. His fierce determination culminates in legendary performances on the football field, where he battles Sylvia's brother Lambert in epic contests against Yale.
Graduating into the high-stakes world of Wall Street, George capitalizes on the outbreak of the First World War to build a massive fortune alongside Lambert and his college roommate Goodhue. As his wealth and influence rival those of the old elite, George finally breaches the Planter inner circle. Yet, as he maneuvers closer to Sylvia in the glittering drawing-rooms of New York society, he must confront the emotional hollowness of his triumphs and the true cost of the walls he has built around his heart.
