Isaac Newton and Edmund Halley travel to London to present before the Royal Society, England's brotherhood of scientists, in the hope of attaining membership. Unbeknownst to Newton, Halley is a spy for the English crown and is tasked with stealing an equation discovered by Newton that may predict the future. Newton, meanwhile, meets Sophia, a beautiful Prussian royal who has her own aspirations to become a Society member. As he pursues Sophia's affections, Newton makes his greatest discoveries: calculus, the laws of motion, and love.
