“Jekyll & Hyde” concerns a brilliant doctor whose experiments with human personality create a murderous counterpart. Convinced the cure for his father’s mental illness lies in the separation of Man’s evil nature from his good, Dr. Henry Jekyll unwittingly unleashed his own dark side, wreaking havoc in the streets of late 19-century London as the savage, maniacal Edward Hyde. He manages to kill scores of people without getting caught. Finally as Jekyll is about to marry his lover, Emma, he turns into Hyde and kills a wedding guest. In the end, Hyde/Jekyll begs his friend Utterson to kill him. Utterson holds a blade to Hyde/Jekyll's heart but cannot harm his friend. However, Hyde/Jekyll falls forward onto the sword, committing suicide.
