Plot: Jay (Smith) and Kay (Jones) are back, protecting the earth from the scum of the universe. It’s four years later, and Kay has become a civilian again (working in a post office), with no memory of his Men In Black exploits. Jay, meanwhile, is a top Men In Black agent now, and uncovers a diabolical plot led by Serleena (Boyle). Jay finds that only Kay has the information to save the world, and goes to bring him back in. Now Jay must convince Kay that aliens do exist, again, and bring him back into the Men In Black.
