So Bruce Wayne aka Batman (Ben Affleck) has decided to gather the league of heroes to save the planet. Enter Wonder Woman (Gal Gadot), Aquaman (Jason Momoa), Cyborg (Ray Fisher) and Flash (Ezra Miller) to help him. But someone is missing; where is the Man of Steel when you need him? He can't be dead based on that final scene from Batman v Superman: Dawn Of Justice; there's no sign of Superman for now but we do see a glimpse Lois (Amy Adams) in this trailer so it's safe to assume that he will turn up at some point to help the league.
Fueled by his restored faith in humanity and inspired by Superman's selfless act, Bruce Wayne enlists the help of his newfound ally, Diana Prince, to face an even greater enemy. Together, Batman and Wonder Woman work quickly to find and recruit a team of metahumans to stand against this newly awakened threat. But despite the formation of this unprecedented league of heroes-Batman, Wonder Woman, Aquaman, Cyborg and The Flash-it may already be too late to save the planet from an assault of catastrophic proportions.
