Batman gives the viewer a brief reminiscent of his early days as a crime fighter, his time with Robin Dick Grayson, how he became Nightwing and how a new Robin Damian Wayne came to be. In the present day, Batman and Robin begin chasing after Penguin and Harley Quinn and succeed in entrapping Penguin in a magnetic cage. After Harley and Poison Ivy are defeated, Batman leaves Robin with the defeated criminals and chases after a criminal who resembles a ninja. After cornering the criminal in an alleyway, Batman is able to deduce that the criminal is Nightwing who used the ninja costume to try and lure Batman into a surprise birthday party which disappoints Nightwing Dick Grayson along with the other attendees of Batman's party (consisting of Robin Damian Wayne, Batgirl Barbara Gordon, Justice League members Superman, Wonder Woman, and Cyborg, and Teen Titans members Beast Boy and Starfire). Batgirl, Robin and Nightwing reveal that as a present for Batman, they decided to take him on vacation. Superman is willing to serve as a temporary replacement of Batman, believing the criminals of Gotham would not be hard to defeat due to many of them lacking superpowers. The Justice League and Teen Titans are able to convince Batman to accept the vacation and Batman, Nightwing and Batgirl leave to their holiday plans. Robin stays behind to show Superman the ropes and give him advice on Gotham's villains. Meanwhile at Arkham Asylum, Joker uses a spoon (which he drew a face on and calls "Spoony") to dig himself out of his cell. Elsewhere, Batman easily figures out Nightwing and Batgirl's vacation plans for him, to take him down Memory Lane by having him visit the dojo of his former martial arts sensei Madame Mantis. After a brief reunion battle with his former sensei, Batman discovers it was actually a disguised minion of Deathstroke. Batman, Batgirl, and Nightwing then find Deathstroke and follow him into a cave. Meanwhile in Gotham City, Superman finds out about Joker's escape and ignores Robin's warning about him. Unfortunately, this allows Joker to trick Superman into freeing Harley Quinn, Penguin, Poison Ivy and Scarecrow from Arkham. Superman calls Cyborg in hopes of gaining assistance to stop the escaped villains...
