After three years confinement in a psychiatric hospital, former Chief Inspector of the
Sûreté Charles Dreyfus has recovered his sanity and has been cured of his obsession with killing Inspector
Jacques Clouseau, who has replaced Dreyfus as Chief Inspector. Dreyfus is elated when informed by his psychiatrist that he is to appear before the sanity board that afternoon pending release. Clouseau arrives unannounced to speak on behalf of his former boss, promptly subjects Dreyfus to a series of mishaps and within five minutes manages to drive him insane again. Dreyfus later escapes from the hospital and again attempts to kill Clouseau by planting a bomb in Clouseau's apartment block while the chief inspector (by periodic arrangement) duels with his manservant Cato. Although the bomb destroys Clouseau's apartment and injures Cato, Clouseau, as usual, manages to escape uninjured. Deciding that a more elaborate plan is needed to eliminate Clouseau, Dreyfus enlists the help of several career criminals and abducts professor Hugo Fassbender, a renowned nuclear physicist, and his daughter Margo. Dreyfus forces Fassbender to build a "
doomsday weapon" in exchange for their freedom. Clouseau travels to Britain to aid
Scotland Yard in the investigation of the kidnapping. While in the Fassbender home, Clouseau wreaks havoc when attempting to interrogate the domestic staff, including Jarvis, Fassbender's cross-dressing butler. After Jarvis is killed by the kidnappers, to whom he had become a dangerous witness, Clouseau discovers a clue that leads him to the
Oktoberfest in
Munich. Meanwhile, Dreyfus appears on worldwide television, warning of a possible holocaust and as a demonstration of the incredible power he possesses, the
United Nations Building in New York City, will vanish from the face of the earth. One week later, the UN building is disintegrated using Fassbender's doomsday weapon and Dreyfus threatens to destroy an entire city unless Clouseau is eliminated. In response, several nations order their operatives to Munich to assassinate Clouseau in hopes of gaining Dreyfus's favour and possibly Fassbender's invention. As a result of their orders and Clouseau's obliviousness and ineptitude, all of the assassins kill each other until only the agents of the
Soviet Union and Egypt remain. One of Dreyfus's henchmen, disguised as Clouseau, is killed by the Egyptian assassin after being mistaken for Clouseau. The Egyptian is seduced by Russian operative Olga Bariosova, who makes the same mistake and falls in love with him. After the Egyptian hitman departs, the real Clouseau returns to his hotel room. He is surprised to find Olga in his bed and is perplexed by her affections. With her help, Clouseau ascertains that Dreyfus is hiding out at a castle in
Bavaria and immediately goes there. After his arrival, Clouseau's initial attempts to sneak into the castle are foiled by his usual ineptitude. Dreyfus, meanwhile, is suffering from a
toothache but is elated by the erroneous report of Clouseau's demise. After learning that a dentist is needed at the
castle, Clouseau disguises himself as an elderly German dentist and finally gains entry to the castle. Unrecognised by Dreyfus, Clouseau intoxicates both of them with
nitrous oxide. While both are laughing uncontrollably, Clouseau mistakenly pulls the wrong tooth and Dreyfus immediately deduces that the inept dentist is Clouseau in disguise. Clouseau escapes, and a vengeful Dreyfus prepares to use the machine to destroy England. Clouseau, eluding Dreyfus's henchmen, unwittingly foils Dreyfus's plans when a medieval
catapult outside the castle launches him on top of the doomsday machine, causing it to malfunction and fire on Dreyfus and the castle. As the occupants of the disintegrating castle, including Fassbender, Margo, and Clouseau escape, Dreyfus plays "
Tiptoe Through the Tulips" on the castle's
pipe organ before he and the castle vanish into thin air. Returning to Paris, Clouseau finds Olga waiting for him in his bed. However, their tryst is interrupted first by Clouseau's apparent inability to remove his clothes, and then by Cato's latest surprise attack, which causes all three to be hurled into the river
Seine when the reclining bed snaps back upright and crashes through the wall. Immediately thereafter, a cartoon image of Clouseau emerges from the water, unaware that a gigantic Pink Panther, Jaws agape, is waiting below (a reference to the recent film
Jaws). The animated Clouseau chases the Pink Panther up the Seine. == Cast ==
