Exhausting his final lead in a current case, Batman sneaks into Stonegate Prison in order to question a connected prisoner who refuses to talk. Once there, he realizes that a trap has been set by prison kingpin MR. BIG, who comfortably runs his criminal network from within his cell. As word spreads of the Batman's presence, a riot ensues. Pursued by worn enemies furious for revenge, Batman fights his way through the bowels of the prison, only to be captured and marched down Death Row and strapped into the electric chair. Luckily, The Riddler springs him at the last minute, not about to have the honor of besting Batman robbed from him by a bunch of low-life jailbirds.
