While the rest of the Suicide Squad is busy with their undersea exploits in Atlantis, Amanda Waller ships Captain Boomerang down under on a mission to save his home country! Someone's planted nukes all across Australia, and it's up to Boomerang to hunt them down with an old friend from the Australian Secret Service. It's one last mission as Captain Boomerang: Agent of Oz, and he's got a license to give a bloke a right kicking!
