In 1884 Munich, young Albert Einstein's curiosity is sparked by a brass compass, igniting a lifelong fascination with the hidden forces of the universe. As he grows older, he struggles against the rigid conformity of the German school system, finding solace in the absolute truths of mathematics and geometry. Facing mandatory military conscription at fifteen, he ultimately makes the daring choice to abandon his homeland.

After renouncing his German citizenship to avoid military service, a young Albert struggles academically before finally gaining admission to the Zurich Polytechnic. Free to pursue his radical ideas about physics, he settles into his new life and catches the eye of a mysterious fellow student who will alter his path forever.

Facing mountain debts, academic rejection, and a secret pregnancy, Mileva Marić and Albert Einstein struggle to survive in isolation as their professional prospects crumble. When an unexpected offer at a patent office provides a potential lifeline, Albert must decide if taking a low-level desk job can save his hidden family from ruin.

While working as a low-level clerk at the Bern patent office, Albert secretly develops groundbreaking physics equations during his spare time. With the support of his friend Michele Besso, he completes four revolutionary manuscripts that challenge classical mechanics and mails them to a prominent scientific journal.

In 1905, Albert Einstein experiences a series of groundbreaking revelations about time, mass, and energy, drafting four revolutionary physics papers from his garret parlor. After mailing his manuscripts to a premier German journal, he endures months of agonizing silence while waiting for a response. His patience is finally tested when an official letter carrying the seal of the Prussian Academy arrives.

When Max Planck publicly validates Albert Einstein's theories, the obscure clerk is instantly propelled to global academic renown. Instead of celebrating his newfound fame, Albert becomes consumed by a relentless effort to map the curvature of space and gravity. His dangerous obsession with complex mathematics pushes him to a breakthrough, but ultimately destroys his marriage to Mileva.

As World War I erupts, Albert Einstein stands alone against German nationalism while racing mathematician David Hilbert to complete his general theory of relativity. After deriving equations that perfectly explain Mercury's orbit, his revolutionary theory catches the attention of British astronomer Arthur Eddington across enemy lines. Risking blockades and ocean storms, Eddington prepares a dangerous expedition to test the German outcast's predictions and prove a new vision of the universe.

Arthur Eddington leads a 1919 expedition to West Africa to photograph a total solar eclipse and test the theory of general relativity. The developed photographic plates confirm that gravity bends starlight, catapulting Albert Einstein to instant global fame. However, this sudden worldwide renown also draws dangerous political backlash and anti-Semitic threats in Berlin.
