Men in Black follows the exploits of Agents K (Jones) and J (Smith), members of a top-secret organisation established to monitor alien activity on Earth. The two MIB find themselves in the middle of a deadly plot by an intergalactic terrorist (Vincent DOnofrio) who has arrived on Earth to assassinate two ambassadors from opposing galaxies. K and J face a simple imperative; track down the interloper or the Earth will be destroyed. Its all in a days work for the Men in Black.
