A scientist working on an important new invention which will protect Allied shipping from U-boat torpedoes has been assigned Secret Service security protection. Amazingly, despite the fact that his laboratory and experiments are located on the upper floor of his Washington mansion, he decides to host a cocktail party for friends on the first floor. Even though several of his guests are foreign nationals with shadowy pasts, he refuses to allow his bodyguards to attend because their presence might offend them. When he is killed by unknown means before joining them, the resultant summary investigation includes Honolulu detective Charlie Chan and children Tommy and Iris, later joined by Birmingham Brown, the chauffeur of one of the guests. When a preliminary autopsy reveals the scientist was electrocuted, Charlie and his associates must decide which of the suspects and red herrings is the guilty party.

Charlie and son Jimmy visit an exotic Rio nightclub in the company of local police chief Suoto in order to arrest nightclub chanteuse Lola Dean, whom Charlie believes killed her paramour a year earlier in Honolulu after discovering that he was married. Rather than cause a public scene, the always discreet Chan decides to wait until she gets home. By the time the minions of the law arrive, they find the singer has been stabbed to death, her jewels stolen, and a bevy of clues seemingly planted at the crime scene. Among the suspects are the singer's companion, an ex-husband, a Dean friend along with her boyfriend, an amateur sleuth, her rich playboy fiancée, a rival for his affections, a mind-reading mystic, and, of course, the butler.

Because Charlie Chan plans to return to Honolulu, he no longer needs the services of Birmingham, who gets a job as butler for William and Justine Bonner, two apparently phony psychics who regularly host occult activities in their home. When Charlie's pretty daughter Frances attends a séance out of curiosity, Mr. Bonner is shot, and she becomes an immediate suspect. Charlie postpones his trip home to help with the investigation, which is made problematic when no bullet can be found in the wound and a hypnotized Mrs. Bonner is compelled to commit suicide by jumping off the roof of a downtown building.

When three employees of a bank are found murdered with cobra venom, Charlie Chan connects the homicides to a case he had worked in Shanghai in 1937. Even though he arrested the alleged murderer, whom later escaped from the police, Charlie wouldn't be able to recognize him because, at the time of his apprehension, his badly burned face and hands were swathed in bandages. Although Chan believes he is now involved with a gang that is stealing valuable radium from a bank vault, utilizing tunnels that connect to the area sewer system, his new identity remains a mystery. When a detective disguised as a bank guard is found dead in a tunnel by Birmingham, Charlie knows he's on the right track. Written by duke1029

Coincidence like ancient egg, leave unpleasant odour. Canary unlike faithful dog, do not die from sympathy. Number 2 son very promising detective, promise very much, deliver very little. Nut easy to crack if nut empty. Number 2 son like interest on mortgage, impossible to escape. Fresh weed better than wilted rose. Happy solution never see light if truth kept in dark. One man with gun have more authority than whole army with no ammunition. Door of opportunity swing both ways. Wishful thinking sometimes lead to blind alley. Same leopard can hide beneath different spots. Confidence of son like courage of small boy at dentist, most evident after tooth extracted. Written by Alan Smithee
