Maybe you read it wrong, because the one where J discovered that the woman was an alien was MIB2, the one without cockroaches, the one where K retired as a postal worker, and the last one where the black woman was an alien and returned.

In case you are watching the first one, of course you can't see it. Attached is the plot (although the woman is not mentioned): In "Blackjack 2", Kay (played by Tommy Lee Jones, Tommy Lee

Jones) and Jay (Will Smith) once again joined forces to fight against an evil alien female seductress, building the best, last and only line of defense for people.

.

This sinister woman poses the strongest challenge to the MIB's proud claim to protect the Earth from the pests of the universe.

Four years have passed since the last time the search for extraterrestrial invaders successfully averted a huge intergalactic disaster.

Kai has retired and lived a comfortable civilian life, while Jay continues to work for the "Black Super SWAT".

The "Black Super Police" is an unofficial government agency with a huge fund that manages all extraterrestrial affairs on Earth.

While investigating a seemingly ordinary crime, Jay discovers a diabolical plan planned by the evil master Serleena (Lara Flynn Boyle).

The evil Kylothian monster disguises herself as a sexy lingerie model and enters the headquarters of the Black Power Squad.

When Selina took over the entire building and held everyone there hostage, only Jay escaped.

At this time, Jay can only rely on Kai, his old partner in the former SWAT team, now another huge government agency, enjoying a comfortable life in the United States Postal Service, deliciously tasting the cookies made by his wife and unwilling to pay attention to it anymore.

The battle with alien monsters.

It's a race against time as Jay must convince Kai - who not only has no memory of his previous work for the Dark Force, but who is also the only one capable of saving the galaxy - to return to the Dark Force.

Come to save the earth from destruction.
