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 to execute dangerous black-ops missions, with only Col. Rick Flag and Katana on the ground to make them behave. Their first mission: to stop an ancient and powerful witch known as "The Enchantress", who has possessed Flag's beloved fiancée Dr. June Moone, and is currently being controlled by a twisted mad scientist called "The Thinker" alongside a foreign entity with plans to use her to take over the world.
