The Arrowverse's heroes are called to battle when a global extinction event is being planned by an Apokoliptian being called Darkseid. Superman (Tyler Hoechlin) has faced this enemy before, but when he finds out about darker plans in store, he advises The Flash (Grant Gustin) that a war is coming. To win this fight, they will have to put together a team called the Justice League.
