Batman prefers to work alone–but the Justice League needs him to be a team player if they’re going to keep the World Assembly meeting peaceful. With tensions simmering between two European countries, Batman follows his own instincts instead of working with the group. Hawkgirl demands to go with him, determined to help. But with two clashing styles of fighting, they’re going to have to learn to deal with each other before they can save the world. And that might take more time than the World Assembly can spare.
