Batman prides himself on being a loner, a totally self sufficient one-man band. He is understandably irritated when his nightly cleanup of Gotham City villains is interrupted by Superman, who pesters Batman to join his new Super-Hero team, the Justice League. After Batman makes it quite clear to the Man of Steel that his invitation has been declined, Superman flies off disappointed … whereupon he is overcome with a strange energy and vanishes!
As costumed Super-Villains begin vanishing one-by-one at the hand of a mysterious enemy, the Dark Knight must free the newly-formed Justice League from a powerful foe. But can Batman learn the value of being a team-player before the Justice League is lost forever?
