In 1200 BC ancient Greece, King Amphitryon of Tiryns invades Argos. Amphitryon eventually fights rival King Galenus in personal combat, killing Galenus and seizing his kingdom. Queen Alcmene is disgusted by her husband's thirst for power and warmongering. She prays to Hera for guidance and Hera, wife of Zeus, tells her that she will allow Zeus to impregnate Alcemene with the savior of her people, a demi-god son to be named Hercules. The only other witness to this is Chiron, the queen's loyal adviser. Amphitryon names his new "son" Alcides, though Alcmene secretly acknowledges his true name as Hercules.
Hercules (Dwayne Johnson) is the leader of a band of mercenaries comprising the spear-wielding prophet Amphiaraus (Ian McShane) of Argos, the knife-throwing thief Autolycus (Rufus Sewell) of Sparta, the feral warrior Tydeus (Aksel Hennie) of Thebes, the Amazon archer Atalanta (Ingrid Bolsø Berdal) of Scythia and his nephew storyteller Iolaus (Reece Ritchie) of Athens. Hercules is said to be the demigod son of Zeus, who completed the legendary Twelve Labors, only to be betrayed by Hera who drove him insane and caused him to murder his wife Megara (Irina Shayk) and their children during a visit to King Eurystheus (Joseph Fiennes). Throughout the film, it is not clearly established that Hercules is truly the son of Zeus, and many are skeptical of the claim as well as of the stories of Hercules' famous Twelve Labors. Despite this, Hercules is frequently seen displaying unusual strength and nigh-unmatched skill in combat. Hercules is frequently haunted by the memory of the deaths of his wife and daughters by his hand, as well as visions of Cerberus.
In the summer of 2006, Percy recounts the story of Thalia and her sacrifice. A young Annabeth, Luke, Grover and Thalia are running to Camp Half-Blood while being pursued by monsters. Thalia sacrifices herself to get the others into the camp, and her father Zeus transforms her into a pine tree, creating a magical border around the camp. Soon a Cyclops passes through the border and is revealed to be Tyson, Percy's half-brother. The camp is later attacked by a Colchis Bull who breaks through the border and ravages Camp Half-Blood. Percy defeats it with the help of Tyson, Annabeth, and Clarisse. Following this, Luke Castellan (who had survived his and Percy's battle in the previous film) appears and confronts Percy, trying to convert him to his cause. When Percy refuses, Luke disappears.

La déesse Artémis (Frédérique Barré) a faussé compagnie à l'Olympe et est devenue une jeune femme qui va à la fac à Caen en France. D'abord d'un caractère misanthrope et solitaire, car elle préfère la compagnie des animaux et des enfants à celle des adultes, Artémis voit son quotidien changer lorsqu'elle fait la connaissance de la nymphe Kalie Steaux (autrement dit Callisto, jouée par Noémie Rosset), qui lui propose de prendre une colocation avec elle. Très vite, les deux jeunes femmes se lient d'amitié et entreprennent toutes sortes d'activités et de voyages. Le tout est raconté par un narrateur omniscient (Hubert Viel) qui a parfois un peu de mal à suivre les événements.
Perseus (Sam Worthington), a son of Zeus (Liam Neeson), lives as a fisherman after the death of his wife, Io (portrayed by Gemma Arterton in the previous film), with his young son, Helius (John Bell). Zeus visits Perseus and asks for his help, saying that humans are not praying to the gods and as a result the gods are losing their power and becoming mortal. Perseus realizes the walls of Tartarus are crumbling and Zeus informs him that the imprisoned Titan Kronos will soon be free. Perseus, valuing his family's safety, refuses to get involved.
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 get revenge on the gods for failing to save his family. Hyperion captures the virgin oracle Phaedra (Freida Pinto), believing that she can use her visions to find the Epirus Bow's resting place.
In ancient times after defeating their predecessors, the Titans, the gods divided the Universe among themselves. Zeus took the skies, Poseidon took the seas, and Hades was left with the Underworld upon being tricked by Zeus. The gods created the mortals, whose faith and prayers assured the gods' immortality. As time passed, however, mortals began to question them and soon resist their creators, angering the Olympians.
In New York City, Zeus and Poseidon meet at the top of the Empire State Building, where Zeus reveals that his master lightning bolt has been stolen and accuses Poseidon's demigod son, Percy Jackson, of the theft. Poseidon reminds him that Percy is unaware of his true identity, but Zeus declares that unless his master bolt is returned to Mount Olympus before the summer solstice, in two weeks' time, war will be waged between all the gods.
Centuries ago, the Amazons, a proud and fierce race of warrior women, led by their Queen, Hippolyta (voiced by Virginia Madsen), battled Ares (voiced by Alfred Molina), the god of war, and his army. During the battle, Hippolyta beheaded her son, Thrax (voiced by Jason Miller), whom Ares forcibly conceived with her, who is fighting for his father. Hippolyta then defeated Ares, but Zeus (voiced by David McCallum) stopped her from delivering the death strike. Instead, Hera (voiced by Marg Helgenberger) bound his powers with magic bracers so that he was deprived of his ability to draw power from the aura of violence and death he could instigate, effectively rendering him mortal, and only another god could release him. In compensation, the Amazons were granted the island of Themyscira, where they would remain eternally youthful and isolated from Man in the course of their duty of holding Ares prisoner for all eternity. Later, Hippolyta was granted a daughter, Princess Diana (voiced by Keri Russell), whom she shaped from the sand of the Themyscirian seashore and gave life with her own blood.
Young archaeologist Dr. Valerie Cammon (Polly Shannon) and her colleague Dr. Kim (Philip Moon) go by ship to a volcanic island in the Mediterranean sea.
