Urgent! Ask for a brief introduction to the story. Men in Black 1, 2!

Part One: This film is based on Lowell Cunningham's cartoons. The story happened in the future. Due to the constant wars in the universe, a large number of aliens have taken refuge on the earth. The man in black here is a special policeman who deals with aliens. Their duty is to monitor the aliens living on the earth and what they have done to the earth. This time, they discovered the secret invasion and destruction plan of evil aliens on the earth. Therefore, they are determined to fight a deadly battle with aliens. It was only after the battle that the enemy was discovered to be a destructive insect monster. At the moment when interstellar movies have become popular, this movie gives people a fresh and interesting feeling unexpectedly and has a high entertainment effect. The most successful place is that although it was adapted from a comic book, the director did not treat the audience as idiots while properly creating an exaggerated style. On the contrary, he took pains to convince the audience that the bizarre alien world presented in this film may be true, but most people don't want to believe it. In order to make the story more logical, the director brings the audience into the perspective of Jay played by will smith, and with his adventures, he learns that there is an "alien immigrant world" on earth that has been supervised by American mysterious institutions for decades. Kay, played by tommy lee jones, is responsible for solving this mystery. The development of the plot is not only self-evident, but also wonderful, which is quite different from the modular story processing of other similar science fiction films. Another brilliant point is that Perry Sunnyfield, the director, does not take alien stunts as all the selling points, but focuses on traditional role contrast, humorous dialogue and scene processing. Part II: In Black Police 2, Kay (tommy lee jones) and Jay (Jay, will smith) once again join hands against an evil alien female pervert, and build the best, last and only line of defense for people. This sinister woman's proud declaration of MIB: protecting the earth from those pests in the universe-constitutes the strongest challenge. It has been four years since the last search for alien invaders successfully solved the great disaster between galaxies. Kay has retired and lived a leisurely civilian life, while Jay continues to work for the "Black Super Police". "Black Super Police" is an unofficial government agency with huge funds, which manages all alien affairs on the earth. While investigating a seemingly ordinary criminal case, Jay discovers an evil plan planned by the evil master Serena (Lara Flynn Boyle). This evil Kylothian monster disguised himself as a sexy underwear model and entered the headquarters building of Black Super Police. When Selena occupied the whole building, she took everyone there hostage, only Jay escaped. At this time, Jay had to rely on Kay. He was an old partner of the Black Super Police and now he is a huge government agency. In the U.S. Post Office, he enjoys a wonderful life, enjoying the cookies made by his wife, and ignoring the struggle with alien monsters. This is a race against time, because Jay wants to convince Kay-he not only has no memory of working for the black super police before, but also is the only person who has the ability to save the galaxy-to return to the black super police to save the earth from extinction.
