The Interpreter

The Interpreter is a 2005 political thriller film starring Nicole Kidman, Sean Penn, Catherine Keener, and Jesper Christensen.

A security scare forces the evacuation of the U.N. building, and, as Silvia returns at night to reclaim some personal belongings, she overhearsmen discussing an assassination plot in Ku an EastAfrica dialect she understands. Silvia runs scared from the building when those discussing the plot 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 U.N. security the plots target appears to be Zuwanie himself. They, in turn, call in the U.S. Secret Service, who assign Tobin Keller Sean Penn and Dot Woods Catherine Keener to investigate, as well as protect Zuwanie when he arrives. Keller learns that Silvia has, in the past, been involved in a Matoban guerrilla group, that her parents and sister were killed by land mines laid by Zuwanies men, and that she has dated one of Zuwanies political opponents. Although Keller is suspicious of Silvias story, the two grow close and Keller ends up protecting her from attacks on her person. Silvia later finds that her brother Simon and her lover Xola were killed as shown in the opening scene.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 rushes to the safe room and arrives just in time to prevent Silvia from murdering Zuwanie. Zuwanie is indicted, and Silvia is expelled from the U.S., returning home to Matobo soon afterwards. ........
