Plot
On the island of Themyscira, thousands of years ago, a young Diana asks her mother, Queen Hippolyta, to tell her the story of the New Gods. After the Old Gods, led by Zeus, created the New Gods, a battle began that ended in the deaths of most of the Old Gods. On the New Gods' home planet of Urgrund, a catastrophic event happened that split the planet in two, one called New Genesis, a utopia for the heroic New Gods, and Apokolips, a hellish landscape ruled by Darkseid. Darkseid is on a quest for the three Mother Boxes, hidden on Earth, and once attacked Earth, but the Amazons, the Atlanteans, and the humans worked together to stop him and each one of the three armies took a Mother Box for themselves. The Amazons' is kept in their vault. Hippolyta warns Diana that one day Darkseid will return for them, and she must stop him. Diana promises her she will.

In the present day, on Apokolips, Darkseid is informed by Granny Goodness that the third and final Mother Box has finally been located. Darkseid prepares his army and takes off for Earth, alongside Steppenwolf, Goodness, Glorious Godfrey, and DeSaad.

On Earth, in Gotham City, Bruce Wayne/Batman chases a thief attempting to escape his grasp. However, before Wayne can stop him, a Parademon, sent by Darkseid, appears and scares away the thief. Wayne fights the creature but after pinning it down, it vanishes, leaving behind a pile of dust. He returns to the Batcave with the dust and has Alfred Pennyworth begin uncovering what the dust is made out of.

In Metropolis, journalist Clark Kent writes a piece on why Batman must be stopped, but his chief editor Perry White scraps the article, not wanting to slander Batman. This angers Kent, but he gives up, and returns home to Lois Lane, who tries to get him to see the good in Batman.

In Washington, D.C., Diana is now working for A.R.G.U.S., a secret organization specializing in superhuman threats. Director Amanda Waller is notified of another Parademon attack, and Diana tries to explain the creature to Waller, who is more interested in finding Batman. Diana realizes the attacks have been more frequent and, afraid of Darkseid's incoming attack, decides to return to Themyscira.

In Atlantis, King Arthur Curry discovers a disturbance in the water and discovers Steppenwolf and Godfrey. Arthur attacks both of them, but they make it past him and find the Mother Box. Arthur's wife, Mera, tries to stop them, but she is critically injured before they escape. Arthur gets her help, until she pleads with him to go, knowing Darkseid is here.

On Themyscira, Diana tells her mother about the Parademon attacks, but Hippolyta is unconcerned, having deduced it was going to happen soon. As they are talking, Goodness and DeSaad arrive, and the Amazons put up a fight to protect the Mother Box. Hippolyta herself attacks Goodness, and though Diana intervenes, Hippolyta is mortally wounded and DeSaad and Goodness escape with the Box. Diana says goodbye to her mother, who crowns her the new Queen of Themyscira.

In Central City, high school sophomore Barry Allen is walking home from school, when suddenly he notices a meteor-like object crash in the distance. Allen super-speeds to the location of the crash and discovers a green shield surrounding it. He touches it, but is sent flying back, before a man, Hal Jordan, emerges from the shield, dressed in a green costume. Jordan attempts to fight Allen, but the two soon realize neither is the bad guy. Jordan reveals he has come to stop Darkseid, and Allen becomes curious, asking to join him on his journey, and Jordan reluctantly agrees.

In downtown Metropolis, Parademons attack everywhere, searching for Kent. Lois begs him not to go, but he, as Superman, fights back, until Darkseid appears. He reveals that the Kryptonians were some of the only people who could truly put up a fight with him. Kent tries to fight back, but Darkseid only backs down when Batman arrives to distract him. Darkseid is then forced to escape. Wayne and Kent reveal their identities and reluctantly join forces. Both are stopped by Waller, who recruits them for her cause.

On Themyscira, Diana mourns her mother while being crowned as Queen. Arthur arrives and informs Diana of what has happened to Atlantis. They realize what is happening and Diana realizes the last Mother Box is with mankind and she and Arthur decide to return to A.R.G.U.S. for help.

In Wshington D.C., Diana and Arthur arrive at the A.R.G.U.S. headquarters and meet Wayne and Kent. Diana begins trying to locate the final Mother Box, but Waller seems reluctant. Suddenly, Darksied, with Steppenwolf, Goodness, Godfrey, and DeSaad at his side, attacks. Diana, Arthur, Batman, and Superman are able to put up a fight but are clearly outnumbered. Darkseid, followed by Diana, finds the third Mother Box in the basement. Diana attacks him and attempts to grab the Box, but Darkseid, powered by the other two, defeats her. Suddenly, Jordan and Allen show up, and Jordan is able to fight Darkseid. Diana recovers and fights back, with Kent. Allen, Wayne, and Arthur take on Darkseid's minions. Eventually, Jordan steals the Box and teleports Darkseid away.

The six heroes recover, but Diana is angry at Waller for hiding the Mother Box for years. She attempts to apologize, but Diana refuses it. The makeshift team bonds and tries to come up with a strategy. Kent activates the Mother Box, but they cannot access the technology without Apokoliptian DNA. Wayne explores the facility, followed by Allen, until the latter is discovered. Both men stumble onto a room of alien experiments, seemingly dead, until one awakens. Allen is freaked out, but Wayne is curious and releases the alien, a Martian named J'onn, who is fully sentient and able to speak English. He reveals A.R.G.U.S. captured him fifteen years ago after he made his way to Earth and he has been kept there ever since.

Darkseid orders DeSaad to get him the third Mother Box right away, as he combines the two other Mother Boxes into a larger object, which he uses to set up a base in Metropolis, closing it off from the rest of the world, and trapping Lois and White.

Kent wants to go to Metropolis immediately but Waller orders him to stand down. Wayne and Allen return with J'onn. Diana becomes completely disillusioned with Waller, and she and the other heroes separate themselves with J'onn, who informs them of Darkseid's history. The catastrophe that destroyed Urgrund was also Darkseid's creation, as he chose power over family. The team decides to split up as Kent, Wayne, and Allen go to Metropolis, and Diana, Arthur, Jordan, and J'onn stay behind to hack into the Mother Box.

Outside of Metropolis, Allen manages to speed into the city and distracts Darkseid long enough to lower the shields, allowing Kent and Wayne inside. Kent finds Lois and gets her to safety, while Wayne goes to Darkseid's ship and fights Steppenwolf and Goodness. Allen is captured by Darkseid and sent to Apokolips.

Diana talks to Waller, who claims she had no idea the Martian project was going ahead. Diana is forced to believe her for the moment due to the ongoing attack, while J'onn reveals he can shapeshift, and transforms into Darkseid, in an attempt to use Apokoliptian DNA for the Mother Box. It does not work.

Wayne learns Allen has been sent to Apokolips, and informs Diana, who realizes they can send someone to Apokolips with the Box and activate it there. Jordan flies the Mother Box to Wayne, who attacks Darkseid and is sent to Apokolips, where he rendezvous with Allen. The two find a civilization nearby and activate the Box there.

Diana, Arthur, and J'onn travel to Metropolis and Jordan gets them inside. Together, with Kent, the heroes fight an empowered Darkseid, who has the extreme upper hand. Wayne and Allen manage to deactivate the Mother Boxes remotely, depowering Darkseid long enough for Diana and Kent to beat him. They then use the Mother Box to turn the Parademons onto Darkseid, killing him with his own army.

Wayne and Allen return to Earth and Steppenwolf, Goodness, Godfrey, and DeSaad are sent back to Apokolips. The Mother Boxes are returned to Themyscira and Atlantis, but Wayne takes possession of the third. The world becomes more accepting of superhumans while the team decides to keep in contact. Diana agrees to continue working with A.R.G.U.S. as long as she is made known of every ongoing project and secret. Her identity as Wonder Woman also becomes known due to the battle, along with Green Lantern, Aquaman, and Martian Manhunter. The seven heroes together are collectively dubbed the Justice League.
