"The Justice League of America--the greatest heroes of Earth--first united to protect mankind from the gravest threats and most dangerous villains imaginable. But what happens when some of those very villains break into the League's headquarters...looking for protection? A covert task force has been kidnapping super-powered criminals and transporting them off-planet--where they're never heard from again. To avoid this fate, powerful super-villains led by The Key and Dr. Polaris come to the Justice League seeking sanctuary. But by taking the villains under their protection, the Justice League incurs the wrath of the government-backed Suicide Squad--leading to the League's most controversial battle yet!" -- P.  of cover.
