The Batman 2022

On Halloween, Gotham City mayor Don Mitchell Jr. is murdered by a man calling himself the Riddler. Reclusive billionaire Bruce Wayne, who has operated for two years as the vigilante Batman, investigates alongside the Gotham City Police Department (GCPD). Lieutenant James Gordon discovers a message that the Riddler left for Batman. The Riddler kills commissioner Pete Savage and leaves another message for Batman.

Batman and Gordon discover that the Riddler left a thumb drive in Mitchell's car containing images of Mitchell with a woman, Annika Koslov, at the Iceberg Lounge—a nightclub operated by the Penguin, mobster Carmine Falcone's lieutenant. While the Penguin pleads ignorance, Batman notices that Selina Kyle, Annika's roommate and friend, works at the club as a waitress. When Annika disappears, Batman sends Selina back to the Iceberg Lounge for answers and discovers that Savage was on Falcone's payroll, as is district attorney Gil Colson.
