An image of a bat appears every night in the night sky of Gotham City - the sign of Batman. Everyone who at least once saw him could no longer forget: in some he inspired faith and hope; in others, it was the fear that made them tremble and look back as they went about their dark criminal deeds. Batman continues his war on crime, inspiring the citizens of Gotham to do good. But the people of Gotham are a crowd. As you know, the crowd is often stupid and ungrateful, it goes where it is led: Batman - the Dark Knight - to purification, the new district attorney - the White Knight - to an ideal society, and the villain Joker - to Chaos. And the Joker is fulfilling his mission better than the knights of Gotham... With the help of loyal allies: Alfred, Lucius Fox and Lieutenant James Gordon, Batman will stop the destructive wave of crime raised by the insidious experimenter Joker. But it will cost him too much. He will lose many close people. And perhaps even your life...
