The plot, like the book, focuses on the fairly calm, intelligent and well-respected Dr. Jekyll, a London physician who struggles to control his horrific and fiendish evil side named Mr. Edward Hyde, the demon he's created from a serum concocted in his laboratory. The battle between Jekyll's good and bad sides and the victims that get caught in that clash, while Jekyll's acquaintances attempt to unravel the mystery of just who is Edward Hyde, form the basis of this engaging tale.
