An assassination attempt on Lisa strikes Matt instead and leaves him hospitalized and fighting for his life. While Robert tries to hide the events from the press, Jackson is forced to work with the chief of counterintelligence to determine who ordered the attack on Lisa and how her position at the CIA was uncovered. Eventually, Lex admits to indirectly blowing Lisa's cover to the assassin and, in the process, unknowingly giving him access to information on Lisa. However, Lex soon redeems himself by leading Robert and Jackson to the terrorist organization behind the shooting. As Matt hangs on to his life by a thread, Lisa contemplates a leave of absence from the CIA.
