London, 1893 — a city drowning in fog, fear, and bloodless corpses. When noblemen, scholars, and government officials are found drained of blood with occult symbols seared into their skin, the great detective Sherlock Holmes is called to investigate. But what begins as a case of gruesome murder soon spirals into a confrontation with something beyond logic... and older than time.

Holmes and Dr. Watson uncover a hidden trail leading to a secret society obsessed with immortality, and a name whispered in hushed tones: Count Dracula.

As Holmes delves deeper into the shadows, he finds himself drawn into a battle not just of reason and superstition—but of mind and soul. Torn between science and the supernatural, he must confront an adversary who feeds not only on blood, but on curiosity, memory, and fear.

Will the world's greatest detective survive the one mystery he cannot solve? Or will he become the very thing he's sworn to destroy?
