Amanda Waller recruits and threatens an unconventional team of disgruntled villains to try to stop a presidential assassination and election by the shadow organization, Leviathan. But they don't and end up causing more chaos. The attack was carried out with a Kryptonite bullet, and they have to figure out why and find who did. Lex Luthor takes advantage of the chaos and takes the reigns, entering the race for President (thus precipitating the events in the Superman and Batman films). Of course, he wins, and it turns out Waller set everything up to help Luthor achieve his goals.
