When Batman finds himself under attack by his own son, Damian (Robin), he at first suspects the hand of Ra's Al Ghul behind the treachery, but then comes to see that the boy may be controlled by a mysterious and murderous society known as the Court of Owls.

The leader of the League of Shadows, Ra's al Ghul, and his daughter Talia, oversee an army of assassins with plans for world domination. A planned uprising within the ranks threatens the balance of power and sends Talia and her young son, Damian, fleeing to Gotham City. Talia seeks the protection of Batman, Damian's secret father. Batman must wage war against Deathstroke and the League, all while teaching the headstrong boy that one can't fight crime...

During their investigation into Bruce Wayne's disappearance, even Alfred goes undercover to assist, and soon they all become involved with the mysterious Batwoman, who may have been the last to see Batman alive. As the Bat family continues to track him down, they come to the inescapable conclusion that the Dark Knight has gone over to the dark side, becoming Gotham's newest and most deadly crime boss.
