London, 1800. The mild and highly respected Dr. Jekyll discovers a formula that can transform him into his opposite self, Mister Hyde, a primordial, evil, and repugnant creature that acts out of his most basic and violent instincts. Two different natures coexist and confront in one mind, hopelessly split between the inclination to the Good and the allure of Evil. And the wild drive to the crime is taking over more and more, making him prefer the dark slums of London to his sunny living space. Through Science the Doctor tries to rule and keep separate the two opposite lives, but the searing memory of the atrocities Hyde is commiting slowly devours Jekyll’s life.
