Terrorists are threatening to destroy 13 sites in the U.S. Two couples stand in their way. Chelsea Merrill, Presidential aide, joins Secret Service agent, Jasper Peters-Templeton, when a list of hit sites, intended for her because of her access to the President, is found on the body of a double agent. Meanwhile, Donnell McKinnon, Interpol, has been assigned to guard imperious rock star, Charm Dumotte. She and her concert-goers have been threatened by al-Qaeda. She has no idea why until Donnell discovers some Arabic writing on the back of some lyrics she wrote while killing time at a bistro in Rome. When Charm's concerts arrive in America, Donnell quickly discovers that the two cases are related. Joining forces with Jasper's secret service team, they stay only one step ahead of the terrorists even after Chelsea breaks the code of the combined lists. The final denouement takes place at Charm's concert in Charleston, South Carolina. Determined to kill her for interfering with their plans, Charm is personally attacked before the concert; however, the second step of their plan is to fly a small plane loaded with explosives from the private airport nearby into the Coliseum during Charm's concert. But Charleston is not the only site of attack. The two couples must depend on others to save the lives of their families as well as millions of Americans.
