The last Pink Panther film to star Peter Sellers before his untimely death. French mobster Philippe Douvier, suffering from a lack of respect in the crime community, orders the murder of Chief Inspector Clouseau, who has been hailed as a genius. After the assassination attempt, a dead body is found in Clouseau's car and everyone - including Clouseau's former superior, Charles Dreyfus - believes Clouseau is dead. Feeling much better, Dreyfus is released from the mental hospital that Clouseau drove him to in the first place. But Clouseau is not dead and goes undercover together with his trusty manservant Cato to discover who tried to kill him.
