Synopsis
THE DIMENSIONAL RIFT LOOMING OVER CENTRAL City is closed, thanks to last-second heroics from the Flash and Team Arrow. But they still have plenty of chaos to deal with: Cisco and Curtis are lost in time, a maniac is terrorizing the citizens of Star City, and the Flash is running out of options to save everyone. And when Anti-Matter Man arrives on Earth-38, the Flash and his friends race across dimensions to join forces with Supergirl, and Superman, and their allies at the DEO - but even with all hands on deck, will it be enough to stop a force of pure decay?
