An army of aliens known as the Timeless have attacked Earth, unleashing a wave of destruction throughout history, and the Justice League is the only one powerful enough to stop them. But the League has been separated and divided by time and by crucial moments, and if the Timeless manage to destroy those moments, superheroes will never have existed. From Wonder Woman and Aquman at Olympus to Cyborg in the remote 31st century, each member of the group faces an overwhelming threat alone. All except Martian Manhunter Shazam and Superman, who traveled together to the end of the time wave to confront its source. With the existence of the Man of Steel's wife and son in danger, can the world's greatest heroes save Earth's history? Or has the Justice League run out of time?
