We see Steppenwolf and his army wreak havoc on Earth including on Wonder Woman's homeland, Themyscira.

But the Metahumans are seen rising to the occasion. Cyborg (Ray Fisher) and Batman offer to be Aquaman's (Jason Momoa) ride while battling Steppenwolf's army. Wonder Woman (Gal Gadot) and The Flash (Ezra Miller) clear the path for Batman. Basically, the whole team is working together.
