A double bill of alien chasing. In 'MIB', after chasing a fugitive with an advanced alien weapon, New York cop James Edwards (Will Smith) finds himself recruited to the MiB, a top secret agency in charge of alien immigration on Earth. He is partnered with K (Tommy Lee Jones), and sent to investigate an alien prediction of the end of the world. They have to track down a hostile alien life form currently wearing the human skin of a country hick named Edgar. Whilst in 'MIIB' it is some four years later and K (Lee Jones) has returned to a civilian life, working as a postman and quite unaware of his former heroics alongside Agent J (Smith). But when J uncovers a secret alien plot organised by the seemingly seductive Serleena (Lara Flynn Boyle) he has to call on K again. Unfortunately K has no memory of his former role as 'Saver-of-the-World', but somewhere in his head is the expertise that can save the Earth, if only J can get him onside in time.
