Black Adam
In 2600 BC, the tyrannical king Ahk-Ton of Kahndaq enslaves his people to mine the mythical metal Eternium, using it to forge the Crown of Sabbac to attain power and invincibility. After attempting to stage an uprising against Ahk-Ton, a young slave boy is chosen as champion by the Council of Wizards, transforming him into an adult superhero. He kills Ahk-Ton, ending his reign.
In the present day, Kahndaq is oppressed by the criminal organization Intergang, as Adrianna Tomaz, an archaeologist, tries to locate the Crown of Sabbac with her brother Karim and colleagues Samir and Ishmael. Inside the tomb, Adrianna obtains the crown, but the Intergang troops kill Samir. As a last resort, she reads an incantation that awakens the superhuman warrior Teth-Adam from slumber. US government official Amanda Waller deems Adam a threat; after he slaughters the Intergang troops, she contacts the Justice Society to apprehend him. Justice Society members Hawkman, Doctor Fate, Cyclone and Atom Smasher stop Adam's killing spree and explain to Adrianna that Adam was not a savior but an imprisoned killer.
Ishmael reveals himself as the leader of Intergang's Kahndaq division as well as the last descendant of Ahk-Ton and kidnaps Adrianna's son Amon, who has hidden the crown. The group finds the crown and gives it back to save Amon. Ishmael attempts to shoot Amon, causing Adam to lose control of his powers, killing Ishmael and wounding Amon. Guilt-ridden, Adam flees and reveals to Hawkman that Kahndaq's champion was actually his late son Hurut, who was killed by Ahk-Ton's assassins after they killed his mother. Having been given Hurut's powers to save his life, Adam, blinded by grief and rage, murdered Ahk-Ton and destroyed his palace. Deemed unworthy by the Council of Wizards, Adam killed them all in retaliation except for Shazam, who imprisoned him along with the crown.
Feeling unfit of becoming a true hero, Adam surrenders and the Justice Society takes him to a secret underwater Task Force X black site in Antarctica, where Emilia Harcourt places him in stasis. Fate again has a premonition of Hawkman's impending death. The Justice Society realizes Ishmael tricked Adam into killing him to be reborn as Sabbac, the champion of the six eponymous demons. When Sabbac summons the Legions of Hell to terrorize Kahndaq, the Justice Society unsuccessfully attempts to stop Sabbac. Fate believes that Hawkman's death can be avoided with his sacrifice and fights Sabbac alone. Fate uses astral projection to release Adam before he is killed by Sabbac.
Meanwhile, Amon, Adrianna and Karim rally the people to fight the Legions of Hell. Sabbac overpowers Hawkman, but Adam arrives in time to kill Sabbac, causing the Legions of Hell to disappear. The Justice Society departs on good terms with Adam, who destroys the old throne in the belief that Kahndaq needs a protector, not a ruler. He adopts a new name: Black Adam.
In a mid-credits scene, Waller warns Adam against leaving Kahndaq and sends Superman, who offers to negotiate with him.
