Hidden atop a secret mountain stronghold lies the League of Shadows and it's fearless leader, Ra's al Ghul. Together with his equally dangerous daughter Talia, he oversees a trained army of assassins with plans for global domination. But an uprising from within the league now threatens to shift the balance of power and sends Talia and her young son, Damian, fleeing to Gotham City. With assassins on their trail, Talia seeks the protection of Batman, who, unbeknownst to him, is the boy's father. With his son in tow, Batman wages war against the villain Death stroke and the League of Shadows, all while teaching his headstrong boy that one can't fight crime by becoming a criminal.
