Synopsis for Green Lantern: "At the World's Fair"
Alan Scott attends the New York World's Fair. At the Cafe Condor, he sees a young woman preparing to shoot a man sitting at another table. Alan disarms her and takes her outside. The woman introduces herself as Irene Miller. The man she was prepared to shoot is a gangster named Murdock. Irene explains that her brother Danny once belonged to Murdock's mob, but decided to quit the organization and go straight. Murdock was resentful of Danny's decision, so he framed him for a drunken driving incident, which resulted in the death of a pedestrian. Alan tells Irene that he knows a friend who might be able to exonerate her brother.
Alan charges his ring and changes into Green Lantern. He first stops at the state prison and finds Danny Miller to get his side of the story. He tells Danny that he will bring Murdock to justice and clear his name.
Later, Murdock's thugs stage a riot at the fairgrounds to distract some police officers, giving some of his other goons the chance to rob the proceeds from the Hall of Music. Green Lantern arrives and chases after the thugs as they make their getaway. He causes their vehicle to crash and interrogates one of the thugs. The criminals race back to their boss Murdock, and Green Lantern silently tails them. He discovers that Murdock has been blackmailing a judge named Homer Wake in order to get permits to set up their racketeering operation at the fairgrounds. He also learns that Murdock has kidnapped the judge's young daughter and is holding her captive to ensure his leverage over the judge.
Murdock believes that Wake is the reason why Green Lantern has been interfering in their affairs and sends a hitman to silence him. Green Lantern arrives at Wake's home and stops the thug from killing the judge. He then uses his ring to learn where Murdock is holding Wake's daughter.
Returning to the fairgrounds, Green Lantern finds the young girl inside a small room at the Perisphere. Murdock arrives, and the two get into a fight with each other at the top of the building. During the scuffle, Murdock loses his footing and plummets to the ground below. Before dying, he confesses to framing Danny Miller, and Miller is freed from prison.
