Dr. Jekyll and Mr. Hyde

Jekyll, a scientist with dreams of transforming the world, develops and drinks a potion that separates the good and evil aspects of man. But his experiment goes awry, and he metamorphoses into the twisted and sadistic Mr. Hyde, a creature possessed of only the basest human qualities. Hyde wanders the darkest streets of foggy London, turning the city into a nightmare as he preys on those he encounters. (official distributor synopsis)
