Maximus the Mad has conquered Attilan! And his next target is the entire planet! With the Fantastic Four and the Inhumans as his captives, Black Bolt's crazy brother is on the brink of world domination thanks to his powerful hypno-gun! But the Inhumans still have one card to play! Black Bolt's awesome voice! His booming voice could free the royal family from its prison! Or destroy the whole city! Likewise in a nearby chamber, the FF work feverishly to escape from their confinement! If both super-teams can break out, they'll have a chance to break up Maximus' mad plan of conquest!
