Based on Frank Miller's latest graphic novel Xerxes and told in the breathtaking visual style of the blockbuster &quot;300,&quot; this new chapter of the epic saga takes the action to a fresh battlefield--on the sea--as Greek general Themistokles attempts to unite all of Greece by leading the charge that will change the course of the war. &quot;300: Rise of an Empire&quot; pits Themistokles against the massive invading Persian forces led by mortal-turned-god Xerxes and Artemesia, the vengeful commander of the Persian navy.
