Plot
A group of men with clown makeup break into the Crawford Chemical Plant, which they intend to hold hostage. In the meantime, Batman tries explaining to Robin that a hero can be anyone, and to prove this the members of the Justice League are working regular jobs for a community service day. Flash works as a pizza guy, and John Jones is a substitute teacher at Robin's school. Batman will work as a janitor at Robin's school.

The next day, Robin's class takes a test, with Robin telling his friend Victor Stone about Batman's "new job". As Batman goes to various classrooms to mop the floors, Joker breaks into the school. In the cafeteria, Robin, Victor and their classmates eat lunch, while Batman cleans the cafeteria and Jones is on lunch duty. Shortly after, Joker arrives at the cafeteria. He taunts Victor Stone before launching a missile at him. Batman saves Victor, who is brutally injured. Joker kills many of the students, before Batman and Jones - now turned into Martian Manhunter - attack and stop him.

Batman demands to know why Joker broke into the school and killed the students, to which he redirects Batman to Crawford Chemical. Batman heads there, and fights Joker's henchmen. In the meantime, a dying Victor Stone is taken to his father, who hopes to use advanced technology to save his life. Batman confronts one of the henchmen, who falls from a platform in an attempt to take his own life.

Batman explains to Commissioner Gordon that he created the community service day because he received a tip that Joker may attack Gotham High School, and feels guilty knowing that Joker used the shooting as a distraction. Batman learns that the henchman who took his own life was named Patrick O'Brian.

In a post-credits scene, Joker and Scarecrow - both in Arkham Asylum - discuss a horrid creature that lives in the sewers beneath Gotham.
