Motivated by the faith in humanity he had regained and inspired by Superman’s selfless act, Bruce Wayne enlists the help of his new ally, Diana Prince, to take on an even greater enemy. Together, Batman and Wonder Woman move quickly to try to find and recruit a team of metahumans to fight this new threat. The problem is that, despite the formation of this unprecedented league of heroes (Batman, Wonder Woman, Aquaman, Cyborg, and Flash), it may be too late to save the planet from a threat of catastrophic proportions.
