Four years after
Thaddeus Sivana's defeat,
Hespera and
Kalypso, daughters of the
Titan Atlas, break into the
Acropolis Museum in
Athens to steal the
Wizard's broken staff. Taking it to the Wizard, imprisoned in the Gods' Realm, they force him to repair it and reactivate its powers. In
Philadelphia,
Billy Batson and his "
Shazamily" are drifting apart as they grow up and pursue their interests. Billy is worried about being kicked out of the Vasquez family home when he turns eighteen. In a dream, the Wizard warns him about the Daughters of Atlas, prompting the Shazamily to research them. The Shazamily enter the
Rock of Eternity, where they encounter the sentient pen Steve. It writes about the three daughters of Atlas, and they realize that Anthea, Atlas's youngest daughter, is none other than a girl named Anne. She is someone
Freddy Freeman is going to meet. When Freddy meets Anne, he shows off his superhero self. Hespera and Kalypso arrive with the staff and steal his powers. Billy and the Shazamily try to save Freddy, but the daughters kidnap him, encasing the city within an indestructible dome and trapping everyone inside. He is subsequently imprisoned within the Wizard in the Gods' Realm. The Shazamily asks Steve to help draft a letter to negotiate with Hespera for Freddy's release. Billy meets her at a local restaurant and, although the meeting is initially cordial, she and Kalypso soon fight the Shazamily. Pedro loses his powers during the battle, while Hespera is captured and taken to the Rock. Having planned her capture, Hespera easily breaks out and steals the
Golden Apple, the seed of the
Tree of Life. Meanwhile, Freddy and the Wizard attempt to escape the Gods' Realm with the sympathetic Anthea's help, just as Hespera returns with the Apple. The Daughters argue as Hespera and Anthea want to use the Apple to revive their realm, while Kalypso wishes to plant it on Earth to destroy it. Freddy steals it but is soon discovered. Billy and the Shazamily show up, and Freddy reacquires his powers. Billy and the Shazamily emerge with the Wizard at the Vasquez home, where they reveal their secret identities to their foster parents. Kalypso appears with the dragon
Ladon to acquire the Apple and destroy the Vasquez house. The Shazamily attempts to keep the Apple away from Kalypso, but everyone except Billy loses their powers in the skirmish. Kalypso retrieves it, using it to plant the Tree at
Citizens Bank Park. It then spawns various monsters to attack the city. Hespera and Anthea object to their sister's destructive plan, but Kalypso mortally wounds Hespera and de-powers Anthea. Billy, in despair, asks the Wizard to revoke his powers, but the Wizard assures him that he is a true hero and so worthy of them. Heeding the Wizard's words, Billy flies off to stop Kalypso, while the Shazamily enlists the help of dark
unicorns to fend off the other monsters. Billy persuades a dying Hespera to help him stop Kalypso. Realizing the dome reacts violently to his lightning, Billy lures Kalypso to the park while Hespera shrinks the dome to contain them. Billy sacrifices himself to stop Kalypso and Ladon by overloading the staff with electricity and destroying the Tree and Kalypso's army with it. Hespera acknowledges him as a true god before succumbing to her wounds, causing the dome to disappear. Anthea takes Billy's grieving family to the Gods' Realm for his burial.
Diana Prince, known as
Wonder Woman, appears and repairs the staff. Imbuing it with her power, she uses it to revive the Gods' Realm, restore Anthea's powers, and resurrect Billy. Billy, in turn, uses the staff to restore his siblings' powers. The Shazamily rebuild their home, while Anthea and Freddy start a relationship, and the Wizard takes up residence on Earth. In a
mid-credits scene,
Emilia Harcourt and
John Economos invite Billy into the
Justice Society on behalf of
Amanda Waller, but both turn and walk away as Billy expected an offer from the
Justice League and is annoyed at how similar they sound. In a post-credits scene, a still-incarcerated Sivana encounters
Mister Mind once again, enraged that he has not begun enacting their plan. == Cast ==
