The series takes place two years after the last episode of Batman: The Animated Series. Batman has continued to fight crime in Gotham City, but there have been some changes. Dick Grayson has become Nightwing; Tim Drake has taken over the role of Robin; and Batgirl has become apart of Batman's team. But the Dark Knight's greatest villains continue to plague Gotham City, so not everything has changed.
