Rebirth (1) Batman Beyond : Season 1 Episode 1

In 2019, Bruce Wayne, the original Batman, retires due to failing health when his rescue of a kidnapped woman nearly goes wrong and he must resort to almost using a gun—the ultimate sin in his eyes. Twenty years later in 2039, Terrence "Terry" McGinnis discovers Batman's identity after the aging Bruce Wayne helps him fight off a gang of Jokerz (street punks enamored by the original Clown Prince of Crime). After Terry's father is murdered, Terry seeks Bruce's help to avenge him.
