Introducing the prototype of his newest product to the entire world – the Ion Cortex, a powerful device capable of solving the world’s energy crisis – Bruce Wayne hires brilliant scientist Dr. Jason Burr to work on the project. The announcement also draws the attention of one of the most dangerous groups in the world – the League of Assassins. When one of the League’s deadly assassins, Silver Monkey, attacks Wayne Manor to kidnap Dr. Burr while Batman’s in Gotham, it’s up to Alfred and Katana to keep the assassin at bay until Batman’s return.
