Sal Maroni and Rupert Thorne are struggling over gaining the title of mob cheifton no that Falcone is incompasitated from the scarecrow for the time being. The Joker is a wildcard. He acts out against the mob which in turn causes a mob war. The Joker and the batman have their run ins as well. ROman Sionis will be attacking Bruce in the public light, with Mr. Earl backing him becasue of what wayne did to him. And while Batman/Bruce are under assault, the Joker kills Rachel Dawes sending Bruce into a downward spiral that has him questioning himself and pushes him closer than ever to becoming the very thing that ruined any chance he had for a normal life...a murderer. Oswald "The Penguin" Cobblepot finds it rather proffitable to provide arms to the warring mob factions while notletting the one side know that he is helping his enemy. And an old "friend" pays Batman a visit, to start off the movie.
