Set in fog‑shrouded Victorian London, Dr. Jekyll conducts experiments on deceased women to craft an elixir of immortality.

With each change Hyde grows stronger, threatening to permanently silence the frail Dr. Jekyll.

In the choking fog of Victorian London, Dr. Jekyll prowls the shadowed streets with a mind obsessed by the promise of eternal life. The city’s soot‑gray alleys and gas‑lit corridors pulse with an uneasy mix of scientific ambition and gothic dread, setting a stage where the pursuit of immortality feels both intoxicating and forbidden. Within the cramped walls of his modest flat, a quiet domestic rhythm—his aging mother, her daughter Susan, and her brother Howard—offers a fragile contrast to the relentless experiments brewing in his laboratory.

Driven by the haunting taunt that his research may outlive him, Jekyll fashions a serum from the essence of women who have passed, believing their hormones hold the secret to longevity. When he finally ingests the concoction, the transformation is swift and unsettling: a new, strikingly beautiful persona emerges—Sister Hyde. This alter‑ego radiates confidence and a fierce, almost predatory vitality that stands in stark opposition to Jekyll’s frail, scholarly disposition.

The coexistence of these two selves creates a volatile tension that seeps into every corner of Jekyll’s life. While the gentle presence of his household attempts to anchor him, Hyde’s growing appetite for the very source of the serum pulls him toward the darker underbelly of Whitechapel. The streets whisper of unseen hunters, and the allure of the elixir’s promise begins to blur the line between scientific curiosity and a more sinister, instinctual drive.

As the night deepens over gaslit rooftops, the film lingers on the uneasy balance between brilliance and madness, between a man’s desperate yearning to defy death and the intoxicating, dangerous freedom that his other self embodies. The atmosphere hums with the question of whether Jekyll can ever truly tame the wild, beautiful horror that he has unleashed.
