Batman (Michael Keaton) is back! Since defeating the Joker, Gotham City has enjoyed a moment of peace. However, another powerful opponent has emerged! This time it is the perverse and violent "Penguin". Because he is the second son, "Penguin" was abandoned by his parents since he was a child and became disabled, which made "Penguin" resentful of the entire society. When he grew up, "Penguin" was determined to return to Gotham City, kill all the eldest sons in the city, and control the entire Gotham City. After forcing the evil businessman Max (Christopher Walken) to help, "Penguin" successfully became the mayor of Gotham. At the same time, Max's secretary Celia (Michelle Pfeiffer) accidentally learned their secrets, and when she was persecuted by them, she accidentally gained super powers and became the good and evil Catwoman. Batman will face the dual challenges of "Penguin" and Catwoman this time!
