Johnny Gallagher, a sergeant, is sent from Germany with a prisoner. The prisoner escapes from the men's room at National Airport and Hackman begins his search for his man. Enlisting the help of his ex-wife and various old friends, he finds that the prisoner is part of a plot by senior military personnel on both sides to kill a very high-ranking world figure in order to sabotage arms control talks.
即使叫“惊天动地泣鬼惊神大暗杀”，又如何？。
