A man named Sylvester Pemberton tracks down Chloe and tells her he knows about her team of superheroes and needs their help. However, before he can explain who he is, he is attacked and killed by Icicle. Clark and Chloe's investigation leads Clark to the former headquarters of the Justice Society of America where he meets up with Nelson AKA Dr. Fate, Carter Hall AKA Hawkman and Courtney AKA Star Girl. Courtney pleads with Hawkman and Dr. Fate to help her catch the killer that is targeting their group but they are reluctant to resume their duties as superheroes. Clark, John Jones, Green Arrow and Chloe team up to help the JSA stop Icicle before he murders another member of the group. Meanwhile, Lois receives a package from a mysterious agency called Checkmate, run by Amanda Waller.

Tess creates an elaborate hoax in order to kidnap Green Arrow, and delivers him to Amanda Waller, who tells him that that the government is recruiting him to serve his country. However, Green Arrow escapes before they can reveal his identity. After Oliver brings Clark and Chloe up to speed, the three investigate and Clark is surprised to find John Jones investigating Oliver's kidnapping too. Clark senses that John is keeping information from him. Oliver and Clark are shocked when Tess reveals that Amanda is after something called "Watchtower." Waller threatens to kill Chloe unless Clark gives her the names and locations of the rest of the Justice League.

Tess breaks into Watchtower, triggering an elaborate security system that Chloe installed, ultimately trapping the two women inside. Clark realizes Zod has given his soldiers super powers.
