The Suicide Squad returns with an action packed tie-in to the Batman Death of the Family story! As the Suicide Squad closes in on Basilisk leader Regulus, Deadshot and Harley discover multiple Basilisk sleeper agents within their ranks. Regulus makes one final desparate gamble to save himself by controlling Harley's mind, but Deadshot makes the ultimate sacrifice for his teammate. Harley's lost love the Joker casts a poisonous rain over Deadshot's funeral, leaving only Harley conscious to face the clown prince of crime. Angered and unable to trust Harley because of her relationship with Deadshot, the Joker tests Harley's loyalty, a test which may cost both of them their lives.

As a part of the acclaimed DC Comics—The New 52 event of September 2011, writer and co-creator of the CW show Supernatural Adam Glass rolls out an all-new team of death-row super villains recruited by the government to take on missions so dangerous–they're sheer suicide! The story begins with the Suicide Squad defeated, imprisoned and being interrogated about their newest mission. Harley Quinn, King Shark, Deadshot and company must make it out alive without revealing who's pulling the strings behind their illegal operations. Who will be the first to crack under the pressure? More importantly will they make it all out alive?

It's the Merc with a Mouth in a pulp caper filled with lies, spies and shapely thighs. Codename: Deadpool. He's the CIA's deadliest agent. He's also certifiably insane. In other words, he's the perfect soldier in a Cold War where it's impossible to tell friend from foe and reality from a lie. Wilson is also the only one capable of hunting down a rogue CIA agent and recovering the stolen nuclear suitcase she's carrying before she hands it over to America's enemies.
