William Friese-Green (Robert Donat) is a young British photographer who dreams of making the projection of moving images into a reality. Through various experiments, luck and sheer perseverance, he succeeds in creating a working motion picture camera. However, his achievement fails to capture public attention. Worse, his obsessive devotion to his ambitions causes him to neglect other aspects of his life, leaving William impoverished and causing emotional pain for those closest to him.
