Edge of Sanity

In the opening scene, Henry Jekyll, a young boy, witnesses his father committing adultery with another woman in a barn. His father catches him and violently whips Henry for spying, scarring him for life and leading to repressed sadomasochistic longings. Many years later, in late 1880s England, the adult Dr. Henry Jekyll is experimenting with the human psyche when he accidentally ingests a mix of ether and cocaine and goes insane. He transforms into the monstrous-looking Edward "Jack the Ripper" Hyde and murders a prostitute who resembles one that he previously met as a child. He begins a killing spree using the mixture that was originally meant to be an anaesthesia in order to influence prostitutes and johns to torture and kill each other.<ref name="Dreamt"></ref> The murders gain the attention of a detective from Scotland Yard as well as Jekyll's wife Elisabeth, who begins to suspect where her husband is going at nights.
