Silvia runs from the building when the men become aware of her presence. The next day, Silvia recognizes words in a meeting, where she is interpreting, from phrases she overheard the night before, and reports the incident to UN security; the plot's target appears to be Zuwanie himself. They, in turn, call in the US Secret Service, which assigns Dignitary Protection Division agents Tobin Keller and Dot Woods to investigate, as well as protect Zuwanie when he arrives, as well as Zuwanie's personal head of security, former Dutch mercenary Nils Lud. Keller, whose estranged wife was killed in a car accident just weeks earlier, learns that Silvia has, in the past, been involved in a Matoban guerrilla group, that her parents and sister were killed by landmines laid by Zuwanie's men, and that she has dated one of Zuwanie's political opponents.

The purported assassin is discovered and shot to death while Zuwanie is in the middle of his address to the General Assembly, and security personnel rush Zuwanie to a safe room for his protection. Silvia, anticipating this, has been hiding in the safe room, and confronts Zuwanie and intends to kill him herself. Keller determines that the assassination plot is a false flag operation created by Zuwanie to gain credibility that his rivals are terrorists and to deter potential supporters of his removal. Keller realizes that Silvia returning home means going to the
