The Pink Panther diamond is stolen once again from Lugash and the authorities call in Chief Inspector Jacques Clouseau (Peter Sellers) from France. His plane disappears en-route. This time, famous French television reporter Marie Jouvet (Joanna Lumley) sets out to solve the mystery and starts to interview everybody connected to Clouseau. Each interviewee: Charles Dreyfus (Herbert Lom), Sir Charles Litton (David Niven) and Lady Simone Litton (Capucine) (an ex-wife of Clouseau), George Lytton (Robert Wagner), Hercule Lajoy (Graham Stark), and Cato Fong (Burt Kwouk) tell of their run-ins with Clouseau. She is also kidnapped by mobster Bruno Langlois (Robert Loggia), who doesn't want Clouseau found, but she continues and finds Clouseau, Sr. (Richard Mulligan), Clouseau's father. Is Clouseau alive or is he dead? Each interview has not-yet-seen or famous clips from the previous movies (since Peter Sellers died) as Marie continues to get a honest view or impression of the great French detective.
