Two employees of EDS, a corporation of Ross Perot, were imprisoned in Iran in 1979. Follett describes in tense detail how a team was assembled to resuce them. Many times a plan had to be changed, for example, the plan to remove the men from the prison exercise yard. Because the Revolution had begun, the men were moved to a more secure prison, which caused the team to make a new plan. The last third of the book was the best part.
