Men in Black 3

This is the third movie in the MIB series and is equally entertaining as its previous films. Agents J and K are being spied by Agent O. The alien villain Boris the Animal runs out from a high security prison situated on the moon. His mission is to kill Agent K by travelling in the past time where Agent K has cut his arm by a gunshot.

After knowing the ill-desire of the Alien agent J also travels in the past time to save Agent K from Boris the Animal. This is the main theme of the third movie in the MIB series. Boris uses a secret technology to travel time and undo his defeat from Agent K. This time Agent K gets killed and planet Earth comes in danger as alien species invade on earth. Agent J is the only person travelled back to know the truth of the story and he joins Agent K and repeat the same things that had happened.
Agents J and K are back...in time. J has seen some inexplicable things in his 15 years with the Men in Black, but nothing, not even aliens, perplexes him as much as his wry, reticent partner. But when K's life and the fate of the planet are put at stake, Agent J will have to travel back in time to put things right. J discovers that there are secrets to the universe that K never told him - secrets that will reveal themselves as he teams up with the young Agent K to save his partner, the agency, and the future of humankind.
