A secret government agency led by Amanda Waller assembles a team of imprisoned supervillains, including Deadshot, Captain Boomerang, Killer Croc, El Diablo and Harley Quinn, with the promise of shorter prison sentences under one condition; they are forced to serve the government in suicide missions as Task Force X, with only Col. Rick Flag and Katana on the ground to make them behave. Their first mission: they are assigned to the South American island nation of Corto Maltese after a military coup to unravel a top-secret government project headed by the Thinker.
