Sherlock Holmes, his son, Steel Rod Holmes, and Dr. John H. Watson investigate the disappearance of an antique divan, believed to be part of a drug-smuggling ring led by the nefarious 'Barbecue,' a man who had burned his parents alive during childhood. Sex, drugs and murder all play a part in this adventure, which is highlighted by the over-the-top performance of Todd Jacobsen as the insanely eccentric Inspector Grayson.
