Opening narration
Between the time when the oceans drank Atlantis and the rise of the sons of Aryus, there was an age undreamed-of. And unto this Conan, destined to bear the jeweled crown of Aquilonia upon a troubled brow. It is I, his chronicler, who alone can tell thee of his saga. Let me tell you of the days of high adventure.


Wizard of the Mounds[2]
Conan the Barbarian is a film about a young barbarian's quest to avenge his parents' deaths. The story is set in the fictional Hyborian Age, thousands of years before the rise of modern civilization.[3] The film opens with the words, "That which does not kill us makes us stronger", a paraphrasing of Friedrich Nietzsche,[nb 1] on a black screen followed by a voice-over that establishes the film as the story of Conan's origin.[2][5] "A burst of drums and trumpets" accompanies the forging of a sword,[3][nb 2] after which the scene shifts to a mountain top, where the swordsmith tells his young son Conan about the Riddle of Steel, an aphorism on the importance of the metal to their people,[7][8] the Cimmerians.[9]
The Cimmerians are massacred by a band of warriors led by Thulsa Doom. Conan's father is killed by dogs, and his sword is taken by Doom to decapitate Conan's mother. The children are taken into slavery; Conan is chained to a large mill, the Wheel of Pain. Years of pushing the huge grindstone build up his muscles. His master trains him to be a gladiator, and after winning many pit fights, Conan is freed. As he wanders the world, he encounters a witch and befriends Subotai, a thief and archer.[10][11]
Following the witch's advice, Conan and Subotai go to Shadizar, in the land of Zamora, to seek out Doom.[12] They meet Valeria, a female brigand, who becomes Conan's lover. They burgle the Tower of Serpents, stealing a large jewelâthe Eye of the Serpentâand other valuables from Doom's snake cult. After escaping with their loot, the thieves celebrate and end up in a drunken stupor. The city guards capture them and bring them to King Osric. He requests they rescue his daughter, who has joined Doom's cult. Subotai and Valeria do not want to take up the quest; Conan, motivated by his hatred for Doom, sets off alone to the villain's Temple of Set.[13]
Disguised as a priest, Conan infiltrates the temple, but he is discovered, captured, and tortured. Doom lectures him on the power of flesh, which he demonstrates by compelling a girl to leap to her death. He then orders Conan crucified on the Tree of Woe. The barbarian is on the verge of death when he is discovered by Subotai and brought to the Wizard of the Mounds, who lives on a burial site for warriors and kings.[14][15] The wizard summons spirits to heal Conan[16] and warns that they will "extract a heavy toll", which Valeria is willing to pay. These spirits also try to abduct Conan, but he is restored to health after Valeria and Subotai fend them off.[14]
Subotai and Valeria agree to complete Osric's quest with Conan and they infiltrate the Temple of Set. As the cult indulges in a cannibalistic orgy, the thieves attack and flee with the princess. Valeria is mortally wounded by Doom after he shoots a stiffened snake at her. She dies in Conan's arms and is cremated at the Mounds, where Conan prepares with Subotai and the wizard to battle Doom. By using booby-traps and exploiting the terrain, they manage to kill Doom's cavalrymen. Valeria reappears for a brief moment as a Valkyrie to save Conan from a mortal blow.[8][17] Conan recovers his father's sword during the fight, although its blade is broken. After losing his men, Doom shoots a stiffened snake at the princess. Subotai blocks the shot and the villain flees to his temple.[18]

Closing narration
So, did Conan return the wayward daughter of King Osric to her home. And having no further concern, he and his companions sought adventure in the West. Many wars and feuds did Conan fight. Honor and fear were heaped upon his name. In time he became a king by his own hand.... And this story shall also be told.


Wizard of the Mounds
Conan sneaks back into the temple where Doom stands at the top of a long stairway, addressing the members of his cult. Conan confronts Doom, who attempts to mesmerize him, but the barbarian resists and uses his father's sword to behead his nemesis. After throwing Doom's head down the stairs, Conan burns down the temple.[18] He returns the princess, and the final scene shows him as an old king; the narration says his road to the throne is another tale.[19]
