A force of soldiers and animals is assembled, so massive it shakes the earth when they march. An army, beyond what man had yet to conceive or even imagine in his dreams, marches to devour Greece, led by Xerxes himself, to snuff out the world's one hope for reason and justice. Only three hundred brave souls stand in its path. As Xerxes will painfully find, they are more than men...they are Spartans.
