Behind the black cowl, Gotham City superhero Batman is really millionaire philanthropist Bruce Wayne (Michael Keaton), who turned to crimefighting after his parents were brutally murdered before his eyes. The only person to share Wayne’s secret is faithful butler Alfred (Michael Gough). The principal villain in Batman is The Joker (Jack Nicholson) who’d been mob torpedo Jack Napier before he was horribly disfigured in a vat of acid. The Joker’s plan to destroy Batman and gain control of Gotham City is manifold. First he distributes a line of booby-trapped cosmetics, then he goes on a destruction spree in the Gotham Art Museum while the music of Prince blasts away in the background, and finally he orchestrates an all-out campaign to win the hearts and minds of the Gothamites, hoping to turn them against the Cowled One.
