Get a feel for the busy streets of New York, as described by the picturesque speech of Richard Diamond. Despite his lighthearted banter, he’s quick to let us know that his life is a lonely existance, and that trouble is his business. The hard boiled detective shows a little of his softer side when his girlfriend Hellen phones. She won’t be jealous when a cute dame walks in looking for protection, will she?
Who might be after Miss Knight? ‘Why can’t the cops fill the bill on protecting her? Will Richard’s fee of $100 per day scare her away, or will he feel pity on her? When gangsters come around pushing, and warning him to stay away from Lynn Knight, he takes the case out of spite.
After a close call of nearly being kidnapped with bullets whizzing through the air, Richard takes Lynn to his police detective friend, Walt. Lynn is under wraps, and Richard hits the trail to see what he can find at her place of work. Richard has good luck with a roll of film, but the cops report that Lynn has been abducted. Luck is a finicky thing, and does a few flip flops for Richard. His trail leads to a nightclub, and a pawn shop. Will he find the evidence he needs on that roll of film? Will he live long enough to tell anybody about it?
With a trap set, and bad guys caught, Richard connects the dots for Walt. All that’s left is a few relaxing moments with Hellen as Richard croons, and tries to ease her jealousy over his damsel in distress.
