Covert agents Jay and Kay are back in Black as they reunite to take down the tentacle-tressed Serleena, whose plot to capture the all-powerful Light of Zartha has placed Earth - and its underground Zarthan population - on the edge of catastrophe.

Together the heroic suits dash their way through a heart-pounding race to save the planet from annihilation once again. Nothing short of a standard drill for the MIB, as they protect the Earth from the new scum of the universe.
