A disputed election has divided the nation, and a handful of senior government officials have conspired to have the North Koreans assassinate the President of the United States. Believing the assassination attempt to be only days away, Theresa Deer, Director of the Special Section, a small unit whose existence is known by only a few in the U.S. government, is tasked to interdict the man intent on providing the North Koreans vital information about the president's itinerary for his visit to South Korea. While Deer succeeds in her mission, she is severely injured and finds herself being hunted the North Korean assassins. Clint Smith is sent to Korea to help Deer get back to the U.S. and finds himself caught in a deadly game of cat and mouse with the North Koreans. With no one in the U.S. government to turn to for help, and the South Koreans now also looking for them, Clint approaches a wealthy American widow living in Busan for assistance. Not knowing whether she'll help or not, Clint discovers that he has approached the one person in the city who will bring him face to face to the North Koreans and the endgame.
