Batman: The Killing Joke

He is Batman's most sworn enemy and a ruthless criminal master whose bizarre and violent behavior cannot even be understood by the world's best detectives. But clowns are not born that way. Before he became the Clown Prince of Crime, before his face was completely disfigured and his mind was permanently distorted on that fateful day, he was also an ordinary person that the Dark Knight was willing to sacrifice his life to protect. What caused this ordinary citizen to degenerate into the most powerful villain Gotham has ever seen? Can Batman stop the Joker's plan to drag Commissioner Gordon and his daughter Barbara into the abyss of madness? Can these mortal enemies bring their endless showdown to an end in time?
