In the satirical and ridiculous tradition of Young Frankenstein, funnyman Gene Wilder digs the dirt on classic literature and gives legendary detective Sherlock Holmes a run for his money.  Living in the ever-unfulfilling shadow of his more famous and successful sibling, Consulting Detective Sigerson Holmes (Wilder) is itching to prove himself and leaps at the rare opportunity to help solve a challenging case. As he sets out on a hilarious trail of intrigue and tomfoolery Sigerson is aided by ever-reliable oddball Sgt. Orville Stanley Sacker (Marty Feldman, Young Frankenstein)  he investigates a suspicious opera star-turned-blackmailer (Dom DeLuise, Spaceballs) and becomes involved with a seductive music hall songstress (Madeline Kahn, Blazing Saddles) in a madcap caper of collective calamities.
