Time After Time

In 1893 London, popular writer Herbert George Wells displays a time machine to his skeptical dinner guests, and explains how it works, including having a "non-return key" that keeps the machine at the traveler's destination and a "vaporizing equalizer" that keeps the traveler and machine on equal terms. The police constables suddenly arrive, searching for Jack the Ripper. A bag with blood-stained gloves belonging to Wells' friend John Leslie Stevenson, a surgeon, leads them to conclude that Stevenson may be the infamous killer. Wells races to his laboratory, but the time machine is gone.
