Since the Roman's death, it has been panic in Gotham. The mafia has been disorganized and corpses are piled up in the dark streets of the city. The police and Batman are chasing a serial killer, the mysterious Pendu who leaves on the corpse of his victims sybillins messages whose key remains a mystery. Janice Porter, prosecutor, decides to reopen the Roman's file. In doing so, she stirs up the troubled waters of Gotham's past, awakening ghosts who were only asking to stay asleep. Between Batman and the police, two forms of justice are then opposed. Things are still complicated when Bruce Wayne welcomes under his roof a young boy, Dick Grayson, whose parents have just perished after an unexplained fall. This young trapezist, lost in a world where he has grown too quickly, reminds Bruce of the orphan who, years ago, has sworn revenge for death to Thomas and Martha Wayne, and to bring justice to the cruel streets of Gotham.
