Plot

 * The Anti-Monitor, who originated from the antimatter universe, has been destroying Earths due to an unknown catalytic event. As it is destroying Earth-17, it comes to a head with The Monitor, aided by the Phantom Stranger, who is the only being to coexist in different universes and has the ability to transfer between them. The Anti-Monitor destroys the Monitor, with the Phantom Stranger barely escaping before the universe is destroyed. The Monitor tells Phantom Stranger before he died to recruit heroes and villains from the remaining Earths together to form a strong defensive against the Anti-Monitor. The Monitor dies, and his energy is released to align the remaining dozens of Earths in a formation to potentially merge. An injured Phantom Stranger uses his last ability to transfer to Earth-1.
 * On Earth-1, Batman has flashbacks of Owlman warning him of the anti-matter threat that would destroy the multiverse from Justice League: Crisis on Two Earths. He is working with Cyborg and Mister Terrific on the Justice League satellite to piece together information of this threat.
 * Additionally, the Justice League has been the center of controversy since the events of the last movie. The public is upset by the fact that they decided to help a different Earth. Many governments ended ties with the Justice League. The league itself, however, stays united after Batman helped members settle their differences to stop the Syndicate in Justice League: Crisis on Two Earths.
 * 49 Earths remain in the multiverse. The Anti-Monitor talks to Psycho-Pirate (who was introduced in Hawkgirl: Mysteries in Space) and asks him to lead an army of Shadow-Demons to distract the heroes of Earth-1. He believes that the Justice League of Earth-1 is the strongest out of every Earth.
 * At this point, the membership of the Justice League is very vast. It includes Batman, Supergirl, Shazam!, Aqualad, The Flash, Donna Troy, Cyborg, Big Barda, The Atom, Maxima, Plastic Man, Spartan, Steel, Doctor Fate, Vibe, Booster Gold, Blue Beetle, Black Canary, Mister Terrific, Black Lightning, The Spectre, and Animal Man.
 * The Phantom Stranger appears to several members of the league on the satellite. He warns The Spectre of what is happening. Lex Luthor of Earth-2 also arrives via portal to tell them that their earth now has perfected the technology to transfer between other earths to recruit more heroes to defend the remaining earths.
 * Suddenly, the Shadow-Demons attack Metropolis. Booster Gold, Blue Beetle, Big Barda, and Firestorm help defend it, but are overrun. Blue Beetle is killed by Psycho-Pirate, and Booster Gold rages. Metropolis is evacuated and the Shadow-Demons begin to take over more land.
 * Meanwhile, the Anti-Monitor has destroyed Earths 24, 29, and 30.
 * The Justice League is in complete panic and the world appears to be on the brink of apocalypse. An injured Phantom Stranger, on the brink of death, finds that the Monitor planted an idea in his memory. He tells The Spectre and Supergirl that to find out why the Anti-Monitor rose, you must find the scientist, before perishing.
 * The Spectre and Doctor Fate deduce that the scientist has to do with the ancient experiments being done on the planet Oa. Red Arrow tells them he knows where the current Green Lanterns of the Earth sector are located, and they all meet Simon Baz, Jessica Cruz, and Kyle Rayner (last seen in Green Lantern: Recharge).
 * Mister Terrific and Cyborg deduce that the Anti-Monitor is located in an anti-matter pocket dimension, and they work with Lex Luthor of Earth-2 to modify the Quantum Trigger technology to be able to transport them there.
 * Meanwhile, the Anti-Monitor has destroyed Earths 7, 14, and 25.
 * Simon Baz brings Red Arrow, Doctor Fate, and The Atom to Ganthet on the planet Oa, to learn about the scientist Krona and his multiversal experiments.
 * Batman declares an "all hands on deck" situation and decides to send Justice League members to the various Earths and recruit heroes to bring to the pocket dimension in order to stop the Anti-Monitor and save the multiverse.
 * The Spectre revives Captain Atom, who was killed in The Spectre.
 * Meanwhile, the Anti-Monitor destroys Earths 11, 15, 16, 19, and 27.
 * The Flash, Emiko Queen, Steel, and Black Lightning arrive on Earth-3. They meet Arrow, The Flash, Supergirl, Superman, Speedy, White Canary, Killer Frost, Black Lightning, and Brainiac V. They all return to Earth-1 after some deliberation and fighting.
 * Static, Shazam!, and Batgirl arrive on Earth-4, and recruit Stargirl, Wildcat and Hourman.
 * Batman and Robin arrive on Earth-9 and recruit Batman.
 * Maxima and Aqualad arrive on Earth-8 to recruit Superman.

 * Spartan, Big Barda and Black Orchid are barely able to escape with the Teen Titans of Earth-31 from the Anti-Monitor's destruction and arrive at Earth-1.
 * Other heroes across the multiverse are also recruited.
 * Meanwhile, The Anti-Monitor has destroyed Earths 21, 22 and 28.
 * Martian Manhunter returns to Earth for the first time since The Justice League III with his daughter, Miss Martian. He noticed the Earth in chaos and wanted to help.
 * The Spectre scours the universe to determine what set off the events of the Anti-Monitor's destruction.
 * Psycho-Pirate and the Shadow-Demons have taken over a lot of ground. Other villains in the DCCU have joined him, such as Deathstroke, Felix Faust, Gizmo and New Gods.
 * Ganthet, Simon Baz, Red Arrow, Doctor Fate, and The Atom learn about the scientist Krona (who last appeared in Green Lantern: Brightest Day). He was experimenting in ancient times with time travel and inadvertently created anti-matter. The experiment was shut down by the other scientists on Oa and they created the Green Lanterns to make up for the mistake. The Anti-Monitor kept gaining power over the years and as soon as he became more powerful than the Monitor, he unleashed his attack, hoping to turn the entire multiverse into dark anti-matter.
 * Captain Atom and Martian Manhunter help put an end to the Shadow-Demons. Deathstroke is defeated by the Batmans (Lucas Hedges, Ben Affleck, and Michael Keaton versions). Psycho-Pirate is taken by the Justice League.
 * The Spectre arrives in Oa and brings them and all the evidence back to the Justice League satellite.
 * They force Psycho-Pirate to give details on the Anti-Monitor. The league devise a plan and device to get them all to the pocket dimension and fight the Anti-Monitor in a last-ditch effort.
 * Krona also developed technology for time travel and the league decides to use it for this extraordinary purpose. The Spectre, Mister Terrific, and The Atom time travel back to ancient times and confront Krona, who surprisingly is expecting them. Krona kills The Atom before being restrained by The Spectre.
 * Simultaneously, Lex Luthor of Earth-2 and Cyborg send the heroes to the pocket dimension. They confront the Anti-Monitor.
 * Mister Terrific destroys Krona's invention, but it fails to weaken the Anti-Monitor in present time. Krona laughs, stating that the Anti-Monitor has always existed. His experiment actually created the Monitor, which he hoped the Anti-Monitor would defeat one day to align the Earths (which happened at the beginning of the movie). The alignment of the Earths would allow him to take over multiple Earths with his technology. The Spectre rages out at him, telling him that this has led the Anti-Monitor to go out of control and is on the verge of taking over the multiverse. He also tells Krona that he dies in the War of Light in Green Lantern: Brightest Day and would not experience it anyway. Krona explains that because he invented time travel, he is immortal. Mister Terrific attacks Krona to force him to help destroy the Anti-Monitor.
 * The Anti-Monitor sees the heroes and kills some, mostly from other Earths.
 * On Oa, multiple versions of Krona from different time periods appear and fight The Spectre. Mister Terrific is able to convince Krona that it is for his interest that they must stop the Anti-Monitor.
 * The heroes try to fight back against the Anti-Monitor.
 * Krona gives The Spectre the ability to heighten his powers in the dark anti-matter pocket dimension, and they time travel back to present and enter the dimension.
 * The Spectre goes toe-to-toe with the Anti-Monitor and after a tough fight, the Anti-Monitor is pushed into positive matter and arrives on Earth-Prime, which is a barren planet last seen in Justice League: Crisis on Two-Earths. The Anti-Monitor is weaken in Earth-Prime and an all-out battle begins. Superboy-Prime also arrives to help. Supergirl perishes, however.
 * The Anti-Monitor is destroyed. The heroes return to Earth-1. Superboy-Prime, who has lost everything, appears distraught. The Earths destroyed by the Anti-Monitor were restored and the heroes return to their respective Earths.
 * In the credits scene, Superboy-Prime sees the body of the Anti-Monitor still on Earth-Prime, and smiles.
