Build a movie plot around this: Dreyfus blackmails the leaders of the world into assassinating who? Clouseau
At a psychiatric hospital, former Chief Inspector Charles Dreyfus (Herbert Lom) is largely recovered from the murderous insanity that saw him repeatedly attempt to kill the thorn in his side, Inspector Jacques Clouseau (from the previous Pink Panther films, A Shot in the Dark, and Return of the Pink Panther).
