ELLE is overseeing the startup of MIB’s own SPACE STATION, the BLACKGUARD 1. Alien mercenaries, led by DACK (JEEBS brother), take over the station. Their boss, ALPHA, intends to use the station’s SOLAR CANNON to destroy MIB. Elle sabotages the weapon, buying enough time for KAY and JAY to head into space. The question is: Can the MIB take back the station before Alpha gets the cannon working again?
