Sir Arthur Eddington, a renowned physicist, is challenged by Sir Oliver Lodge to consider Albert Einstein's revolutionary thesis, which questions Sir Isaac Newton's laws. Eddington's initial skepticism gives way to admiration for Einstein's General Theory of Relativity. As tensions rise between England and Germany, Eddington's loyalty is tested as a Quaker refusing to fight. He develops tests to prove or disprove Einstein's theories, while Einstein faces personal struggles, including a failing marriage and opposition to German militarism. Ultimately, Eddington confirms Einstein's theories, marking a turning point in modern physics.
