In Victorian-era London, a clairvoyant police inspector, Fred Abberline, is haunted by the death of his wife and finds solace in opium and absinthe-induced visions. These visions aid him in his work, leading him to investigate a series of brutal and gruesome murders in the Whitechapel district. The victims, all women, are linked by their association with prostitution, leaving the city's underclass in a state of fear and the police force grasping for leads. Abberline's investigation draws him into the dark and seedy underbelly of London, where he discovers that the murders may have connections reaching higher up in society than anyone could have anticipated.

Amidst the backdrop of fear and hysteria, Abberline forms an unlikely alliance with Mary Kelly, a Whitechapel prostitute who seems to be a central figure in the killer's morbid game. As they delve deeper into the mystery, they uncover a conspiracy that threatens to shake the foundations of the English aristocracy and challenge the very fabric of society. With each clue, Abberline comes closer to revealing the identity of the murderer, known only as "Jack the Ripper". Their pursuit becomes a race against time, not just to save Mary Kelly from becoming the next victim, but to expose the truth behind the murders that have thrown London into chaos.
