Power-hungry King Hyperion (Mickey Rourke) and his ruthless army march across Greece, leaving burned-out villages and the corpses of the innocent in their wake. Hyperion's goal is to find the long-lost Bow of Epirus; with this invincible weapon, he can cast the gods out of Mount Olympus and become master of the world. A stonemason named Theseus (Henry Cavill) heeds the words of the sibylline oracle (Freida Pinto), who convinces him that he is the key to stopping the bloodthirsty king.
