After Gabe eliminates Benton, he saves Phagan from assassination only to have him escape. Mara Aramov, now in custody, had attempted to locate PharCom's virus labs. Gabe must set aside the hunt for Phagan to destroy Rhoemer's base in Kazakhstan. During his assignment, Rhoemer seemingly kills Lian, but Agency Director Thomas Markinson rescues Gabe. Markinson gives Gabe a report on the virus called Syphon Filter, a bioweapon that one can program on a genetic level to target specific groups of people. Markinson orders Gabe to infiltrate Rhoemer's stronghold in Ukraine to inject test subjects with a vaccine and locate Phagan, who is now Rhoemer's prisoner. In the catacombs, Phagan tells Gabe that Lian is alive, and they reunite. Lian has become infected with Syphon Filter, and she says there is no universal cure.
