An unlikely trio try to prevent World War III: the U.S. secretary of state in Washington, D.C.; a low-level diplomat in Islamabad; and a stressed-out Navy fighter pilot on an aircraft carrier in the Red Sea.

Alex is captured by Zaman's soldiers and subjected to intense interrogation when they suspect he's working for the CIA. Walter begs the president to delay the air strikes until he can reach someone in the Pakistani government, and Zeke and Glenn continue their high-stakes mission under extreme circumstances.
