Men in Black is a comedy about two special agents who work for Men in Black, an underground agency created to protect earth from tyrant extraterrestrials. Agent K (Tommy Lee Jones) and Agent J (Will Smith), a hotshot, New York City cop, partner to exterminate a villainous alien: "the bug."

Before Agent J relinquishes his police badge to join the Men in Black, Agent K explains the scenario for Agent J, who is still unsure of what the agency does and wants of him.

Agent K explains, "All right, kid, here's the deal. At any given time there are around 1,500 aliens on the planet. Most of them are right here in Manhattan. Most are decent enough. They're just trying to make a living. Humans, for the most part, don't have a clue…."

Agent J asks, "But, uh, why the big secret? Humans are smart. They can handle it."

Agent K answers: "A person is smart. People are dumb, panicky, dangerous animals, and you know it. Fifteen hundred years ago, everyone knew the earth was the center of the universe. Five hundred years ago, everyone knew the earth was flat. And fifteen minutes ago you knew that people were alone on this universe." With a sigh, Agent K adds, "Imagine what you'll know tomorrow."

J asks, "What's the catch?"

"The catch?" K says. "That catch is you will sever every human contact. Nobody will ever know you exist anywhere. Ever." K pauses and then adds, "I'll give you till sunrise to think it over."

As K strolls away, J shouts, "Hey, is it worth it?"

"Oh yeah, it's worth it," K answers, "If you're strong enough."
