Based off of the comic book. Unbeknownst to other people, there is a private agency code named MiB. This agency is some kind of extra terrestrial surveillance corporation. Then, one of the agency's finest men only going by the name "K", is recruiting for a new addition to the agency. He has chosen James Edwards of the N.Y.P.D. Then, one day, a flying saucer crashes into Earth. This was an alien a part of the "Bug" race. He takes the body of a farmer and heads to New York. He is searching for a super energy source called "The Galaxy". Now, Agents J and K must stop the bug before it can escape with the galaxy.
Kay and Jay reunite to provide our best, last and only line of defense against a sinister seductress who levels the toughest challenge yet to the MIBs untarnished mission statement: protecting the earth from the scum of the universe. It's been four years since the alien-seeking agents averted an intergalactic disaster of epic proportions. And now it's a race against the clock as Jay must convince Kay-who not only has absolutely no memory of his time spent with the Men In Black, but is also the only living person left with the expertise to save the galaxy-to reunite with the MIB before the earth submits to ultimate destruction.
