What's the "J.S.A."?

That's right nerds, it's time for the golden age heroes to make their Smallville debut. After the Star-Spangled Kid and the Sandman are murdered by a villain named "The Icicle", the gang gets together in order to find out why he is picking off retired heroes one-by-one. As Oliver pursues a high school girl, Clark and Chloe bust out the Daily Planet archives to learn that this team of heroes were framed for crimes they never committed. That team's name is The Justice Society of America.
