2 years after the events of the previous film, Black Mask is setting up an operation to import a new type of drug into Gotham, with the help of the Penguin. A drug that is more addictive and harmful than anything on the market, called X-Reign, which also gives Black Mask control over all its users. As well as a new Robin taking the mantle after Dick Grayson left to become his own hero. The dynamic duo have to stop him at any cost, with some help from an unlikely source, Catwoman. Meanwhile, Jason Todd is trying to live up to being the ward of Batman, but is too arrogant and cocky to take anything seriously.
