Unlike other Robins, Damian Wayne was trained his entire life as an assassin, and that training fostered brutal methods. As Damian's violent tendencies threaten to end Batman and Robin's partnership, a mysterious killer from Bruce Wayne's past comes to Gotham, looking to end Batman's life.

He calls himself NoBody. He travels the globe in shadow, picking off those he considers guilty and making them disappear without a trace. Now NoBody has targeted Batman for destruction, but first he'll take from him the one thing that matters most. When NoBody offers Damian the chance to give in to his nature, will the newest Robin betray his father to become the assassin he was born to be?
