The Teen Titans, the Flash and the Suicide Squad all collide on Earth-3 — home of the evil Crime Syndicate — on the hunt for former Task Force X mastermind Amanda Waller.
As Waller tries to take over the alternate Earth and dethrone evil versions of Superman, Wonder Woman, Batman, and other heroes that rule it, her former partner — Rick Flag — arrives on E-3 bent on making Waller pay for her crimes, while the Titans and Flash hunt for a missing academy student they believe was kidnapped by Waller to form her mysterious Justice Squad.
