Zack Snyder's Justice League, directed by Zack Snyder, tells how, after the death of Superman, Batman (Ben Affleck) and Wonder Woman (Gal Gadot) decide to recruit Flash (Ezra Miller), Aquaman (Jason Momoa) and Cyborg (Ray Fisher) to build a team of superheroes capable of protecting the world from the threat of Steppenwolf (Ciarán Hinds), under the command of several troops of Parademons.
Enemies want to take possession of the three Mother Boxes, which in the wrong hands could cause damage of catastrophic proportions. But putting on a team proves to be really difficult, because before taking part in the battle against Steppenwolf, each hero will first have to face the demons of their past.
