At a party at Crater Lake, Lois is saved from drowning by Arthur "A.C." Curry. Arthur has incredible swimming abilities, but also a secret agenda aimed at...Lex. Meanwhile, Professor Fine discussed Lex's weapons-manfucturing operations with Clark.

When Lex's Level 33.1 project comes to fruition, Oliver Queen must bring together several of Clark's "heroic" super-powered allies together: Arthur Curry, Bart Allen, and Victor Stone.

Green Arrow calls upon fellow heroes Black Canary and Aquaman to locate the missing Clark Kent, last seen in the Arctic. The Martian Manhunter also joins in to help out.

In an effort to protect the rest of the team, Oliver decides to register for the Vigilante Registration Act to see what the government plans to do with the new law. As he suspected, it was a trap to lure superheroes to an undisclosed location where he is confined to a jail and subjected to a battery of brutal tests under the supervision of Col. Slade. Aquaman and his new wife Mera team up with Clark to free Oliver. Lois is frustrated when Clark continues to push aside her offers to help the team and sets out to prove she can play with the big boys.
