The Justice Society mourns the loss of one of its own—but there's no time to rest. As the dust settles, some of their numbers are still missing, and the Injustice Society is on the verge of fulfilling a plan 80 years in the making. If the JSA doesn't discover the impostor hiding among them and find a way to stop their enemies, the world is doomed!
