Lamont Cranston (Kane Richmond) a.k.a. The Shadow is looking for a missing jade statuette. His investigations lead him into sleazy bars, a doss house and then into a murder scene in his own apartment block! Lamont finds himself accused of the murder though he gets off after outwitting Police Inspector Cardona (James Flavin) - to be honest a piece of cheese could probably do that.
Lamont and his assistant Shrevvie (George Chandler) investigate a complicated plot which the local hoodlum (Jack Overman), his gal (Claire Carleton) and a glamorous model (Jo-Carroll Dennison) seem to be involved in...
It is all fine B-movie detective work and can be a bit Noir-ish at times, what does detract from the movie a bit though is the repetitive humour such as Cardona's stupidity and Lamont's and Shrevvie's jealous girlfriends (Barbara Reed and Jennie Delaney) getting involved to various degrees of non-assistance.
