After the events of Batman: The Killing Joke, Bruce Wayne has found a new sidekick to aid him and Dick Grayson in their adventures as Batman and Robin. That new sidekick is none other than Barbara Gordon, the daughter of the late G.C.P.D Commissioner Jim Gordon, who goes by the superhero alias of Batgirl.
However, a new threat to Gotham reveals itself in the form of former criminal Basil Karlo, who has become the villain known only as "Clayface". Together, Batman, Robin, and Batgirl must defeat this abomination of a monster before he can wreak havoc upon the city.
