The story is about a scientist named Dr. Henry Jekyll who lived in the ancient England (around the 1800s). He starts to hang out with an ugly beast called Mr. Edward Hyde which makes a lot of people surprised. However the funny thing is that Jekyll is Hyde, the scientist invented an elixir which brings out the ugly and brutal side of every human being. Dr Jekyll gets tempted over the fact that he can do whatever he likes in a different disguise and that leads to him getting addicted to (/overusing) the elixir. The story is practically about the ability we humans have towards good and bad things in life.
