It's 1893 London. Futurist H.G. Wells believes that the future holds a Utopian society. He also believes in time travel. He has just built a time machine which he is displaying to a group of skeptical friends, including surgeon Dr. John Leslie Stevenson. Unbeknown to Wells or anyone else among that circle, Stevenson is better known to the public as Jack the Ripper. Just as the police are about to capture Stevenson, he uses the time machine to escape, with Wells being the only one who knows what happened to him.
