The Man of Steel and the Dark Knight return in an all-new adventure -- one in which the fate of the world rests in the balance! Based on Jeff Loeb's popular Superman/Batman comic books, this thrilling film continues the epic saga of the world's greatest superheroes. When a mysterious spaceship from the planet Krypton splashes down in Gotham Harbor with a beautiful girl inside, everyone wants to meet the new kid. Superman embraces this connection to his past, Batman suspects a traitor, Wonder Woman senses a kindred spirit, and Darkseid hopes for a champion. But although her powers are as great as Superman's, this feisty teen has her own ideas, none of which include a secret identity, a cape or any heroics.
