1x3 - The Challenge: ETA

The escalation of ETA reaches an unusual level: car bombs that kill dozens of people, especially guardias civiles. Their aim is to force the government to recognize the independence of the Basque Country. And to do so, it will eliminate anyone who stands in its way, including its dissident members. But the State is reacting with operations that put ETA on the ropes, one of them with the help of the CIA.
