Perseus braves the treacherous underworld to rescue his father, Zeus, captured by his son, Ares, and brother Hades who unleash the ancient Titans upon the world.
A decade after his heroic defeat of the monstrous Kraken, Perseus-the demigod son of Zeus-is attempting to live a quieter life as a village fisherman and the sole parent to his 10-year old son, Helius. Meanwhile, a struggle for supremacy rages between the gods and the Titans. Dangerously weakened by humanity's lack of devotion, the gods are losing control of the imprisoned Titans and their ferocious leader, Kronos, father of the long-ruling brothers Zeus, Hades and Poseidon. The triumvirate had overthrown their powerful father long ago, leaving him to rot in the gloomy abyss of Tartarus, a dungeon that lies deep within the cavernous underworld. Perseus cannot ignore his true calling when Hades, along with Zeus' godly son, Ares (Edgar Ramírez), switch loyalty and make a deal with Kronos to capture Zeus. The Titans' strength grows stronger as Zeus' remaining godly powers are siphoned, and hell is unleashed on earth. Enlisting the help of the warrior Queen Andromeda (Rosamund Pike), Poseidon's demigod son, Argenor (Toby Kebbell), and fallen god Hephaestus (Bill Nighy), Perseus bravely embarks on a treacherous quest into the underworld to rescue Zeus, overthrow the Titans and save mankind.—Warner Bros.

Perseus and his son Helius live as fishermen in a small village. One night, Zeus visits Perseus and tells that the gods are weaker since the humans do not pray to them anymore. He tells that the walls of Tartarus are falling down in the underworld and all the demons will be released on Earth and Kronos will escape from his imprisonment. Zeus goes to the underworld with Poseidon to join forces with Aries and Hades but they are betrayed and Zeus is captured. Poseidon escapes deadly wounded and encounters Perseus in Zeus' Temple. He gives his trident to Perseus and advises him to meet his son and also demigod Agenor in the kingdom of Andromeda and ask him to guide Perseus to find the fallen one. Together with Andromeda, they begin their saga to release Zeus and avoid that Ares and Hades unleash the ancient Titan Kronos.—Claudio Carvalho, Rio de Janeiro, Brazil
Living in self-imposed exile with his only son Helius, Perseus, the demigod slayer of the abominable sea-monster Kraken, is trying to lead a simple life, one long decade after his triumphant victory in Clash of the Titans (2010). However, as humans continue to defy the gods, depriving them of their life-giving faith, the duplicitous lord of the Underworld, Hades, and Ares, the hateful god of war, conspire with the eternally imprisoned Titan, Kronos, to overthrow Zeus. Before long, war breaks out, and Perseus, along with the half-human son of Poseidon, Agenor, and sword-wielding Princess Andromeda, must answer the call to arms and defend, once more, the helpless humans who are on the brink of extinction. Now, the everlasting walls of Tartarus, the impregnable dungeon of torment in the unfathomable abyss, are crumbling. Can Perseus avert the emergence of Kronos the destroyer?—Nick Riganas
Ten years after defeating the Kraken, Perseus (Sam Worthington), the demigod son of Zeus (Liam Neeson), now lives as a fisherman with his 10-year-old son, Helius (John Bell) and has been widowed by the death of Io. One night, Perseus is visited by Zeus, who tells him that the powers of the gods are fading and the walls of the underworld prison of Tartarus are breaking due to the lack of devotion from humans, which is weakening the Gods. Zeus states they will need armies to combat the threat, but Perseus shows little interest and refuses to get involved.
Afterwards, Zeus travels to Tartarus to meet with his brothers Hades (Ralph Fiennes), Poseidon (Danny Huston), and his son Ares (Edgar Ramirez). Hades reminds Zeus that he is still furious with him banishing him to the Underworld when he helped him conquer the Titans and does not show interest in helping Zeus. Zeus tells Hades they must forget the past and unite to rebuild Tartarus' walls, but Hades rejects his offer and orders his minions to attack. They fatally injure Poseidon, and Ares betrays Zeus by taking him prisoner and stealing his Thunderbolt. In an exchange to remain immortal and powerful, Hades and Ares have made a deal with Kronos & plan to drain Zeus' divine power to revive Kronos, the father of Zeus, Hades, and Poseidon. They capture and hold Zeus prisoner in chains and the walls of Tartarus break, unleashing monsters into the world.
After slaying a Chimera that attacks his village, Perseus takes Helius to the Mount of Idols, so they can speak to Zeus, but the dying Poseidon arrives instead. He informs Perseus that Hades and Ares are holding Zeus prisoner in Tartarus and tells him to meet with his demigod son Agenor (Toby Kebbell) to find the fallen god Hephaestus, who knows the way into Tartarus. Poseidon then gives Perseus his Trident before succumbing to his injuries, passing away, and crumbling into dust. Perseus flies on Pegasus to the campsite of Queen Andromeda's army. The queen is the princess Perseus saved a decade ago; Andromeda (Rosamund Pike) has imprisoned Agenor for stealing crown jewels, but Perseus negotiates his release by asking the reluctant Agenor to come along in their plan. Andromeda knows that a war with a monsters is coming.
Perseus, Andromeda, Agenor, and a group of soldiers set out at sea to find Hephaestus, with Agenor explaining that Hephaestus created the three great weapons that Zeus, Hades, and Poseidon wield: Zeus' Thunderbolt, Hades' Pitchfork, and Poseidon's Trident, and that together they form the Spear of Triam, the only weapon that can defeat Kronos. Agenor uses Poseidon's trident to direct the boat to Hephaestus's island, where they encounter three Cyclopes: Brontes, Steropes, and Arges, who attack them.When Perseus shows them the trident, they lead the group to Hephaestus (Bill Nighy), the smith god. He explains that he has a map to navigate the path through a deathly long labyrinth leading deep into Tartarus. He leads them to the door to the Labyrinth, where they are attacked by Ares, who found them after one of the soldiers, Korrina (Lily James), prayed to him. Ares is jealous of Perseus' honor from his own father Zeus and kills all of the soldiers while Hephaestus opens the door and then sacrifices himself so that Perseus, Andromeda, and Agenor can enter the door before it closes. Ares kills Hephaestus with Zeus's bolt while the 3 escape into the door.
Agenor tries to use the map to direct them, but the Labyrinth continually shifts and at one point nearly crushes them. Perseus gets cut off from the group and encounters and kills the Minotaur before finding that he is in the exit of the labyrinth to Tartarus. Eventually, the group manages to reunite and find Kronos becoming powerful. Meanwhile, Zeus has been almost entirely drained of power as Kronos starts to awaken. Zeus apologizes to Hades for banishing him to the Underworld and asks his forgiveness, as he has forgiven Hades for his actions. Though initially surprised, Hades has a change of heart and decides to help Zeus and stop Kronos, but Ares is still angry with his father and Perseus intervenes. Perseus arrives and uses the Trident to free Zeus. As they are escaping, Hades blocks Ares, but Ares takes Hades pitchfork & throws the Pitchfork into Zeus's back, thus mortally wounding Zeus. To escape the charging Kronos, Perseus and Zeus use their powers to Teleport them back to the Tiryns pass, where Andromeda has instructed her army to assemble & this is where battle plans are made.
Perseus, Andromeda and Agenor carry a weakened Zeus down to the base of the mountain where Andromeda's army is gathered. Although the Trident and Pitchfork are now in his possession, Perseus still needs the Thunderbolt from Ares to have the power to defeat Kronos. Perseus intentionally prays to Ares, challenging his brother to a final fight at the Temple of the Gods, which Ares happily accepts.
At the temple, Perseus finds out Ares has kidnapped Helius, who was brought to watch Perseus die in the fight. Ares easily overpowers Perseus, before pushing him into the ruins in the temple, but is distracted when Helius secretly tries to challenge him by pointing a sword at him, giving Perseus the chance to strike back anew. After a struggle, Perseus kills Ares with the Thunderbolt. Ares then crumbles to dust. Perseus and Helius then combine the gods' weapons into the Spear of Triam.
Meanwhile, Andromeda's army is overwhelmed by Kronos' army of demonic Makhai, but Hades arrives to revive Zeus. He and Hades reconcile, and Hades shares some of his immortality with Zeus, making Hades older and Zeus younger, and together they use what power they have left to defeat the Tartarian army. Kronos then appears and begins to attack the human army with lava and fire. Zeus and Hades attack him, giving Perseus the opportunity to destroy Kronos. Kronos lets a blast to try to kill the two, but Zeus jumps into the way, pushes Hades and takes the explosion, wounding him. Perseus then flies down into Kronos' throat and pierces the weapon into his heart, destroying Kronos once and for all.
Perseus meets with Zeus and Hades; a fatally wounded Zeus advises Perseus to use his power wisely, stating that the time of the gods is over. He thanks Perseus for his bravery before passing away and turning to dust. Hades is now mortal, his powers spent, though he states he might be better off as such before heading off to parts unknown. Perseus reunites with Andromeda and kisses her as they prepare for possible Titan reprisal. Knowing that there are still monsters to fight, Perseus decides to train Helius to be a soldier and build a new kingdom.
