Plot.
Years ago, Steppenwolf and his army of Parademons attempt to conquer and remake Earth through the combined energies of the Mother Boxes before they are foiled by a unified army that included the Amazons, Atlanteans and humans. After repelling Steppenwolf's army, the Mother Boxes are separated and hidden in locations around the world.
In the present, the world is in mourning following the death of Superman. Sensing humanity's fear, Steppenwolf and his Parademons return to Earth to resume their hunt for the Mother Boxes through kidnapping several employees of S.T.A.R. Labs, which is in possession of one box. Having investigated the kidnappings and encountered a Parademon himself, Bruce Wayne decides to move forward in recruiting his planned team of metahumans as he believes an invasion is coming.
Steppenwolf manages to retrieve the Mother Box from Themyscira, prompting Queen Hippolyta to warn her daughter Diana Prince. Diana joins Wayne's group and informs him about Steppenwolf and the Mother Boxes. The two of them fail to persuade Arthur Curry and Victor Stone, but manage to recruit Barry Allen into the team. Stone later joins the group after his father Silas is among those kidnapped, and Steppenwolf attacks Atlantis to retrieve the second Mother Box.
The team receives intel from Commissioner James Gordon that the Parademons are traveling underground, and conclude that Steppenwolf's army is based in an abandoned facility. Although the group manages to rescue the kidnapped employees, the facility is flooded during combat, which traps the team until Curry rescues them, having decided to join them after Steppenwolf's attack on Atlantis. Stone retrieves the last Mother Box from S.T.A.R. Labs for the group to analyze. Wayne decides to use the Mother Box to resurrect Superman not only to help them fight Steppenwolf's army, but also to restore hope in humanity. Diana and Curry are hesitant about the idea, but Wayne forms a secret contingency plan.
Clark Kent's body is exhumed and placed in the waters of the Kryptonian ship, and Allen provides a strong energy blast to activate the Box and resurrect Superman. Superman, however, possesses few memories, and he attacks the group after Stone accidentally launches a projectile at him. On the verge of being killed by Superman, Wayne enacts his contingency plan: Lois Lane. Superman calms down and leaves with Lois to his family home where he reflects and tries to recover his memories. With the last Mother Box unguarded, Steppenwolf retrieves it with ease.
Without Superman to aid them, the remaining five heroes travel to a village in Russia where Steppenwolf plans to unite the boxes once again and reshape the world for his nephew Darkseid. The team fight their way through the Parademons to reach Steppenwolf, although they are unable to distract him enough for Stone to separate the boxes. Superman arrives and assists Allen in evacuating the city, as well as Stone in separating the Mother Boxes. The united heroes manage to defeat Steppenwolf, who, overcome with fear, is attacked by his own Parademons, before they are all taken away by a Boom Tube.
In the aftermath of the battle, Wayne decides to rebuild Wayne Manor as a base of operations for the team and he and Diana agree that more heroes could join. Diana as Wonder Woman begins engaging more with the public. Allen manages to acquire a job in Central City's police department. Stone continues to explore and enhance his abilities with his father in S.T.A.R. Labs. Curry returns to Atlantis. Clark returns as a "Daily Planet" reporter and resumes his role as Superman.
