Plot

Theseus is a mortal man chosen by Zeus to lead the fight against the ruthless King Hyperion, who is on a rampage across Greece to obtain a weapon that can destroy humanity.

Eons after the Gods won their mythic struggle against the Titans, a new evil threatens the land. Mad with power, King Hyperion (Mickey Rourke) has declared war against humanity. Amassing a bloodthirsty army of soldiers disfigured by his own hand, Hyperion has scorched Greece in search of the legendary Epirus Bow, a weapon of unimaginable power forged in the heavens by Ares (Daniel Sharman). Only he who possesses this bow can unleash the Titans, who have been imprisoned deep within the walls of Mount Tartaros since the dawn of time and thirst for revenge. In the King's hands, the bow would rain destruction upon mankind and annihilate the Gods. But ancient law dictates the Gods must not intervene in man's conflict. They remain powerless to stop Hyperion, until a peasant named Theseus (Henry Cavill) comes forth as their only hope. Secretly chosen by Zeus (Luke Evans), Theseus must save his people from Hyperion and his hordes. Rallying a band of fellow outsiders, including visionary Priestess Phaedra (Freida Pinto) and cunning slave Stavros (Stephen Dorff), one hero will lead the uprising, or watch his homeland fall into ruin and his Gods vanish into legend.

In Greece, the cruel and evil King Hyperion (Mickey Rourke) is searching with his ruthless army for the Epirus Bow, a powerful weapon made by the Gods, to unleash the imprisoned Titans and destroy the Gods. When King Hyperion comes to the village of the peasant Theseus, he kills his mother and brings Theseus (Henry Cavill) as a slave to work in his mines. However, Phaedra (Freida Pinto) helps to release him with the support of the prisoner Stavros (Stephen Dorff). Meanwhile, Zeus (Luke Evans) advises the other Gods that they should not interfere with the human free will and the last hope of mankind.—Claudio Carvalho, Rio de Janeiro, Brazil

Eons ago, the gods defeated the Titans. Now a new threat has emerged. The evil King Hyperion (Mickey Rourke), is on the warpath searching for a powerful weapon called the Epirus Bow. With this, he can destroy the gods and become the ruler of the world. As villages are destroyed and innocent people massacred, the fate of humanity rests in the hands of the warrior Theseus (Henry Cahill) and the oracle Phaedra (Freida Pinto).—tompeterdaly-63240

Before the dawn of man or beast, immortals waged war against each other in Heaven. The victors declared themselves gods while the vanquished were renamed the Titans and imprisoned beneath Mount Tartarus. The Epirus Bow, a weapon of immense power, was lost on Earth during the war. In 1228 B.C., the mortal king Hyperion (Mickey Rourke) of Heraklion searches for the bow, intending to use it to release the Titans to spite the gods for failing to save his family. Hyperion captures the virgin oracle Phaedra (Freida Pinto), believing that she can find the Bow's resting place.

In a small village nearby, the inhabitants prepare to flee to Mount Tartarus to avoid Hyperion's army. One inhabitant, Theseus (Henry Cavill), is a skilled warrior trained by his mentor, the old man (John Hurt). Theseus and his mother Aethra (Anne Day-Jones), considered undesirables because Theseus was born from Aethra being sexually assaulted, are forced to stay behind by Athenian soldiers including Lysander (Joseph Morgan). Theseus ably battles multiple opponents until the Athenian officer Helios (Peter Stebbings) intervenes and discharges Lysander for his actions. Lysander travels to Hyperion, offering his service and the village's location. Hyperion accepts but maims Lysander for being a traitor. Hyperion's forces attack Theseus' village, murdering the villagers and Aethra, and taking Theseus captive.

The old man, revealed to be Zeus (Luke Evans), meets with his fellow gods Athena (Isabel Lucas), Poseidon (Kellan Lutz), Ares (Daniel Sharman), Apollo (Corey Sevier), and Heracles (Steve Byers), and warns them not to interfere in mortal affairs as gods, believing that, until the Titans are released, they must have faith in mankind to defeat Hyperion.

Theseus is enslaved alongside the thief Stavros (Stephen Dorff). Phaedra, who is held captive nearby, sees a vision of Theseus. Phaedra organizes a riot, using the chaos to escape with Theseus, Stavros, and the other slaves. Theseus decides to pursue Hyperion and attempts to capture a boat, but he and his allies are overwhelmed by Hyperion's forces. Poseidon purposefully falls from Olympus into the ocean, causing a tidal wave that wipes out Hyperion's men. Phaedra sees another vision of Theseus standing near a shrouded body. She determines that Theseus must return home to bury Aethra.

While laying Aethra to rest, Theseus discovers the Epirus Bow embedded in nearby rock. He frees the Bow but is attacked by Hyperion's henchman the Minotaur (Robert Maillet). Theseus kills Minotaur and uses the Bow to save his allies from being executed, before collapsing from poisoned scratches inflicted by Minotaur. Phaedra tends to Theseus and later falls in love with him, stripping her of the visions she deemed a curse. The group returns to Phaedra's temple while Hyperion and his forces are away at Mount Tartarus. At the temple, Stavros and Theseus are lured into an ambush, and Theseus loses the bow. Outnumbered by Hyperion's men, Ares directly intervenes to save Theseus, and Athena provides the men with horses to reach Mount Tartarus. Zeus arrives and angrily kills Ares for disobeying his command. Zeus tells Theseus that they will receive no more aid from the gods, and he must justify the faith Zeus has in him alone. The lost bow is brought to Hyperion.

Theseus, Stavros, and Phaedra travel to Mount Tartarus. Theseus tries in vain to warn Hellenics' King Cassander (Stephen McHattie) of Hyperion's plans, but Cassander dismisses his talk of gods as myth, intending to negotiate peace with Hyperion. The following day, Hyperion uses the Bow to destroy Mount Tartarus' seemingly indestructible wall killing Helios. Theseus leads the Hellenic army to war against the Hyperion forces, killing Lysander. Hyperion ignores the battle and storms through to Mount Tartarus killing Cassander. Hyperion uses the Bow to breach the mountain and free the Titans before Stavros and Theseus can stop him.

The force of the release knocks the mortals down. Stavros takes the Epirus Bow and kills a Titan but is massacred by the other Titans. Zeus, Poseidon, Athena, Heracles and Apollo arrive and battle the Titans while Theseus fights Hyperion. Zeus destroys the Epirus Bow with the Warhammer of Ares. The gods prove more powerful than the Titans, but they are overwhelmed by the sheer number of Titans with all but Zeus and Poseidon being killed. Theseus kills Hyperion, and Zeus collapses Mount Tartarus before ascending to Olympus with Athena's body.

The collapsing mountain wipes out Hyperion's men. The mortally wounded Theseus is transported to Olympus for his sacrifice and given a place among the gods. Several years later, Theseus' story has become legend and Phaedra has given birth to Theseus' son Acamas (Gage Munroe). Acamas is met by the old man who informs the child that in the future, he too will one day fight against evil. Acamas sees a vision of the sky filled with gods and Titans fighting with Theseus among the combatants.
