Tot nu toe was de Justice League een losse vereniging van superkrachtige individuen. Maar wanneer ze worden meegesleurd naar Warworld, een plaats van eindeloze brute gladiatorengevechten, moeten Batman, Superman, Wonder Woman en de anderen zich op de een of andere manier verenigen om een onverslaanbaar verzet te vormen dat in staat is een hele planeet naar de vrijheid te leiden.
Nee, helaas is Justice League: Warworld nog niet beschikbaar op Netflix in Nederland.
