It's H.G. Wells (Malcolm McDowell) versus Jack the Ripper (David Warner) in the fanciful Time After Time -- and, per the film's title, the chase extends from the 19th century to the 20th. Wells has built a time machine in his cellar, which the Ripper uses as a means of escape. Both men find themselves in 20th century San Francisco, and, after a period of adjustment, they make themselves at home. The plot takes a dark turn when the Ripper, disappointed that Wells' dreams of a Utopian future have not come to fruition, resumes his murderous activities.
