Earth's Impossible Day! It's July 4th and as everyone in Midway City celebrates Independence Day, Shiera Hall is sad because this is the same date as the Thanagarian holiday of Impossible Day. Carter tries to cheer her up by suggesting that in celebration of Impossible Day, they should go out as Hawkman and Hawkgirl and have a picnic, and try and pull off some impossible tasks.
Sure enough, when they are having their picnic, they become aware of a forest fire, and use their wings to create a waterspout from a nearby body of water to put out the flames. Next, a bunch of crooks who have rigged their getaway car with some kind of force field are stopped by Hawkman and Hawkgirl, who find fragments of Fulgurite to throw at the vehicle. Upon impact the Fulgurite would create lightning at that ultimately immobilizes the vehicle allowing the authorities to arrest the crooks inside.
Finally, when a Cylix suddenly becomes invisible, Hawkman and Hawkgirl stumble upon a plot of another crook who has been using a device that makes things invisible to steal items from the Midway Museum. Going after the crook as Hawkman and Hawkgirl, the crook tries to kill them with an invisible rifle that fires invisible bullets. Somehow, Hawkman and Hawkgirl were able to dodge the shots and capture the crook. Later, it's revealed that they were wearing special contact lenses that allowed them to see the radiation emanating from any of the invisible objects.
