Batman: Blackgate (1996)

Argumento

Follow Batman on an undercover mission into Gotham's biggest powder keg! Blackgate Prison is a cauldron of seething violence and hatred that's about to blow at the command of one man--unless the Dark Knight can somehow determine who he is and stop his plans cold. But word of Batman's infiltration has reached the mastermind, leading to rising tensions and escalating uncertainties as he--and the readers--try to determine which of Blackgate's three new arrivals is in fact the Dark Knight.
