Ray Palmer and a professor discover that the “X Element” that exists at a sub-atomic level is decaying and will be gone completely in four hours. Apparently all other elements are dependent on it which means the end of the world! Atom informs his fellow league members when suddenly alerts come in across the world as the ramifications of the decaying element begin to take effect. The JLA spread out across the planet to assist.
Later a huge spacecraft arrives and the occupants, known as The Treasurers, announce that they have been observing Earth’s difficulties and offer to help reverse the decay of the X Element. However, in return for their assistance they provide a list of things they want as collateral. The list of random objects seems to make no sense but as per the government’s request the JLA fan out to acquire them.
However, one of the things on the list is kept secret from the league – bizarrely the aliens want a man named George Arthur Stuart! The military quickly arrive on the doorstep of the rather surprised elderly gentlemen. But what do the Treasurers want with him?
