"THE BLACK VAULT" part 2! What was meant to be a routine mission to retrieve a "cosmic item" from an undersea fortress has become a nightmare beyond anything the Suicide Squad ever expected. And with half the team down, it's up to Harley Quinn, Katana, and a demon-possessed graphic designer named June Moore to save the Squad from the most dangerous man in the DC Universe. That's right...they're screwed.

The back-up story will be "Captain Boomerang: Agent of Oz," in which Amanda Waller digs deep into the implausibly impressive origins of the Suicide Squad's most loathsome member to discover the truth the world has been asking for: just who made Boomerang a captain anyway?
