After the Metropolitan Police fail to apprehend the serial killer Jack the Ripper, Sherlock Holmes is approached to investigate the recent murders of prostitutes in the Whitechapel district of London. Helped by Dr. John Watson and the medium Robert Lees, Holmes discovers that all the victims were companions of Annie Crook, a woman locked in a mental institution.
Members of the police hierarchy and several politicians, all Freemasons, seem to be protecting one of their own. Furthermore, Inspector Foxborough, the policeman who is in charge of the case, is in fact the secret leader of the radicals, a political movement waiting for the British government to fall because of its inability to solve the Whitechapel murders. Holmes must rely on his skills to find and confront the murderer.
