Vanessa Webber of the Department of Domestic Security is convinced that Chloe Sullivan, who has been hacking into top secret government systems in an effort to help Clark locate Brainiac and Kara, is a terrorist. She forces Jimmy Olsen to help her expose Chloe’s “hidden secret” by threatening to put him in jail if he doesn’t assist her in bringing Chloe to justice. After Chloe backs out of a promised lunch date with him, Jimmy starts to suspect that his girlfriend might be living a secret life. He breaks into the Isis Foundation, where Chloe has been working since losing her job at the Daily Planet, and discovers that she has been hacking into top level government computer systems on a regular basis. Meanwhile, a new message suddenly appears in Dr. Swann’s journal when Clark goes to read it. It tells him to go to the Fortress of Solitude. After Clark arrives at the Fortress, he hears a scrambled message from Kara that indicates she is presently on Krypton and that Brainiac wants to kill him. This message puzzles Clark since Krypton had been destroyed years ago and couldn’t possibly still exist.
Lex opens the Veritas group’s lockbox in Zurich, finding a compass in a hidden compartment. Just as he’s about to leave, a man attacks him. Lex successfully fends off the attack and escapes from Zurich with the compass and a new, mysterious enemy.
Having had second thoughts about betraying Chloe, Jimmy tries to cellphone her a warning message, but Vanessa intercepts him. She informs him that Chloe intends to conduct an act of terrorism at the grand opening of the Ace of Clubs evening lounge at the Metropolis Satellite Center that evening. Vanessa wants Jimmy to stop her in the act. Having found out that Jimmy hacked into her computer, Chloe decides to ask him to be her date for the lounge opening in order to keep an eye on him. Unbeknownst to Jimmy, Chloe intends to use the satellite on top of the building to try and get the location of Kara and Brainiac. After the two share a dance at the club, Chloe slips off to download the information she needs from the satellite. With Jimmy onto her, she manages to thwart his attempt, angering Vanessa enough that she decides to go after Chloe on her own. After Chloe refuses to tell her what she’s up to, Vanessa roughs her up until Jimmy makes a daring save. Though Chloe is worried that they will now go to prison, Jimmy assures her they won’t thanks to a secret pact he made with someone.
In the end, Lex assures Jimmy that he will owe him a favor for getting Vanessa to drop her investigation. Clark tells Chloe what happened at the Fortress. After looking over the information she downloaded from the satellite and combining it with what Clark heard at the Fortress, the two are certain that the message Clark heard was from 1989 - a warning that Brainiac intends to kill Clark before he is sent to Earth.
