Henry "Harry" Jekyll is a well respected member of London society. In his personal life, he is pre-engaged to Muriel Carew, the daughter of a brigadier general. In his professional life, he is a medical doctor, scientist and academician. He theorizes that in each man is a good side and an evil side which can be separated into two. In doing so, the evil side can be controlled and the good side can live without worry, in combination leading to the betterment of society. In his experiments, he uses himself as the subject to test his hypothesis. His evil side, who he coins Mr. Hyde, escapes into London, and terrorizes party-girl Ivy Pierson. Jekyll, aware of Hyde's goings-on, decides to stop his experiments because of the suffering he has caused Ivy. What Jekyll is unaware of is how ingrained Hyde is in Jekyll's life.
