"...in 'Justice Insurgence' part one, after the harrowing events of 'Dark Nights: Metal' #3, the 'Justice League' has scattered around the world to find the only artifacts that can fight back against the invasion of the 'Dark Multiverse'.
"'The League' thinks they know how to take back their world, but they are not prepared for who is standing in their way. The 'Seven Dark Knights' of the Dark Multiverse.
"All the brilliance of 'Batman', but none of the morals. 'Barry Allen', 'The Fastest Man Alive', is the first to get a taste of their plan, as 'Batman: The Red Death' takes him on at the 'Fortress of Solitude'..."
