The plot concerns the origin of Robin and of the Batman and Robin team. It begins with the murder of Bruce Wayne's parents in the past, shows a montage of his time as Batman, and then shows how in the present day he has become the masked vigilante, Batman, as a result. After the circus acrobat parents of Dick Grayson are murdered by a gangster during a performance in Gotham City, the orphan is put into the care of Bruce Wayne and his faithful butler Alfred by Commissioner Gordon. As the various villains of Gotham team up to defeat their nemesis, Wayne reveals his identity to Grayson and eventually teaches him properly to channel his anger—to seek justice, not revenge. The new pairing is sorely tested when the Joker reveals his master plan to release the inmates of Arkham Asylum into Gotham, and to use Grayson as bait in a final deadly trap for Batman. With the Riddler, the Penguin, Poison Ivy, Two-Face, Scarecrow, Harley Quinn, Mr. Freeze, Killer Croc, Bane, and even Batman's potential love, the thief Catwoman, all ranged against them as well, the new 'Dynamic Duo' faces the ultimate showdown.
