Spain, 1973. Dictator Francisco Franco has ruled the country since 1939 with an iron fist; but he is now a very old and sick man. The future of the weakened regime is in danger. Admiral Carrero Blanco is his natural successor. The Basque terrorist gang ETA decides that he must die to prevent the dictatorship from continuing.
