Publicly shunned and ostracized by the "Firm" and the London Times for unethical legal reasons beyond their control, Sherlock Holmes and Dr. John Watson are forced into the private sector to which may very well be their last case together. On a cold and rainy October Sunday afternoon at the end of the 19th Century-our two fine private detectives are formally solicited by a leading British scientist Dr. Charles Landers on investigating and recovering stolen top secret government plans which could bring an end to the British Empire. Throughout their investigation and without any formal assistance from Scotland Yard and the Home Office-Holmes and Watson will make great leads in the case and meet up with a key witness of such feminine appeal and finally discover the true sole sinister mastermind and chief architect from their past who's behind this world shattering heist.
