The third installment of the Sellers-Edwards Pink Panther saga sees the return of both the first film’s titular diamond and its villain, the Phantom (Plummer, replacing David Niven). When the pink rock goes missing from its home at the National Museum of fictional Lugash, Clouseau bumbles into a world of frame jobs, political maneuvering, and bored wives. The question, as ever, remains whether it will be his own crazy boss, Chief Inspector Dreyfus, who finally does Clouseau in.
