When Charlie and son Lee stay at Monte Carlo for an art exhibition (Lee's become a painter now), naturally they also visit the famous casino; where we soon get to know two exchange sharks, Gordon Karnoff and Paul Savarin, 'fighting' grimly even at a game of Baccara, while at the same time, Karnoff's wife Joan is in a tight spot: she took some of his metallurgic bonds out of his safe and for some strange reason gave them to bartender Al Rogers - and Karnoff intends to send those bonds to the stock market that same night to be sold, which would mean enormous losses for Savarin. She manages to recover the bonds, and her brother Gordon, Karnoff's secretary, places them back in the safe with the others, and so, after being checked, they're all sent by car to France. But when Charlie and Lee happen to come along that same road, they find the car stopped, the courier murdered, and the chauffeur missing...
So, eagerly, Monsieur Joubert from the Monaco police takes on the case - but very soon, he's in despair: the chauffeur is also found murdered, and literally everybody involved in the whole affair could be guilty: Savarin of course, who on top of it all was seen with pretty young Evelyn (who over the past few months suddenly became a rich socialite from the humble model she was before) near the scene of the crime, Joan and the mysterious bartender, her brother Gordon who had access to all of Karnoff's papers - and even Karnoff himself, because very soon the fact is revealed that those bonds were of course insured. A VERY hard nut to crack for Joubert! But Lee has got an even bigger difficulty to cope with: the French language, which he's supposed to have learned at college... Once his desperate tries to express himself correctly even get him and his father into jail on a murder charge! So there are Lee and Joubert to provide the comical elements, while Charlie's calm reasoning finally leads to the capture of the murderer; not the most ingenious of plots, but some very fine performances, and of course some VERY wise philosophical remarks of our Chinese master sleuth...
This is the last 'Charlie Chan' movie starring Warner Oland, because unfortunately he died just a few months later. But we shall never forget that he left to the world 16 MAGNIFICENT performances, which would forever shape the character of our favorite Asian detective - and which will live on for generations and generations to enjoy.
