Agents K and J, members of a top-secret organization established to monitor alien activity on Earth, find themselves in the middle of the deadly plot by an intergalactic threat that has arrived on Earth to assassinate two ambassadors from opposing galaxies.
The Men in Black are back to save the world from a total intergalactic disaster. When a renegade Kylothian monster disguised as a lingerie model threatens the survival of the humanity, the MIB get the call to step up and get busy.
Agents J and K are back...in time. J has seen some inexplicable things in his 15 years with the MIB, but nothing perplexes him as much as his wry, reticent partner. When K’s life and the fate of the planet are put at stake, J will have to travel back in time to put things right.
