Set in a world where the Clown Prince of Crime has been cured of his madness, BATMAN : WHITE KNIGHT follows the man now known as Jack Napier as he embarks on a quest to heat the city he once terrorized. After reconciling with his long-suffering partner, Harley Quinn, he sets in motion a carefully plotted campai, to discredit the one person whom he views as Gotham City's true enemy : Batman. His crusade exposes a decades-long history of corruption within the Gotham City Police Department and transforms Napier into a city councilman and civic hero.
But when the sins of his past return to threaten everything that he has accomplished, the distinctions between savior and destroyer begin to break down for both the Joker and Batman alike—and with them any hope for Gotham's future.
