Everything is connected: an 1849 diary of an ocean voyage across the Pacific; letters from a composer to his friend; a thriller about a murder at a nuclear power plant; a farce about a publisher in a nursing home; a rebellious clone in futuristic Korea; and the tale of a tribe living in post-apocalyptic Hawaii, far in the future.
Two hundred and fifty years in the future, life as we know it is threatened by the arrival of Evil. Only the Fifth Element can stop the Evil from extinguishing life, as it tries to do every five thousand years. She is assisted by a former elite commando turned cab driver, Korben Dallas, who is, in turn, helped by Prince/Arsenio clone, Ruby Rhod. Unfortunately, Evil is being assisted by Mr. Zorg, who seeks to profit from the chaos that Evil will bring, and his alien mercenaries.
