THE TWO FACES OF DR. JEKYLL

In London in 1874, Dr. Henry Jekyll's wife, Kitty, is secretly involved with his friend Paul Allen, who frequently borrows money from Jekyll. Ignoring the warnings of his colleague and friend Dr. Ernst Littauer, the middle-aged, mild-mannered Jekyll concocts a chemical potion which he hopes will help him learn the depths of the human mind.

By testing the potion on himself, he transforms into Mr. Edward Hyde, a young and handsome but also murderous and lecherous man. Soon, Hyde becomes bored with conventional debauchery and when he sets his eyes on Kitty, he decides he must have her. When Kitty rejects him, Hyde rapes her and leaves her unconscious. When Kitty wakes up in the bed, she immediately notices that Hyde has scratched her neck in various places. Distressed, Kitty walks over to a table, where she finds a note written to her. When Kitty goes into the other room looking for Paul, she finds her lover dead, bitten by a venomous snake which Hyde had locked in a room with him. Kitty walks to the patio, puts her leg over the balcony, covers her ears in response to the loud music playing from the party and allows herself to fall off the balcony and through the glass roof covering the party guests. Hyde kills Maria, an exotic dancer he had been having an affair with, in Jekyll's house.

The next day, Jekyll is horrified to learn of what Hyde has done. After speaking to his other half via a mirror, Jekyll turns uncontrollably into Hyde. Hyde kills a man in Jekyll's laboratory by shooting him in the back and sets his body up at a desk in order to frame his other self for his crimes. Hyde sets fire to the laboratory as the police arrive. Via a window, Hyde pretends that Jekyll is trying to kill him as the building burns. After escaping the building, Hyde claims Jekyll tried to kill Hyde and ended up shooting himself due to madness, as the innocent man and Jekyll's laboratory burns.

Some time later, Hyde, Littauer and the police attend the coroner's court, where it is found that Jekyll was responsible for the deaths due to his dangerous experimentation with drugs, and that he then took his own life. Hyde tries to leave the building, but at the last minute Jekyll fights him from the inside and takes over again. As Dr. Littauer recognises his old friend, Dr. Jekyll sits on a bench and is surrounded by astonished people. With tears in his eyes, he says that only he could stop Hyde, and that he has now destroyed him. The police move forward and arrest him for his crimes.

Hyde frames Dr. Jekyll for his crimes, but Jekyll regains control just in time to be arrested for Hyde's actions.

The ending underscores the tragic consequences of Jekyll's hubris and scientific obsession, as his quest to understand the duality of man leads to his own ruin. By giving in to his darker impulses, Jekyll is ultimately consumed by them, with the authorities unable to separate the man from his monstrous alter ego. It’s a bleak meditation on the futility of trying to control one's inner demons.
