The Invisible Line

In 1968, Txabi Etxebarrieta, a brilliant university student from Bilbao, joins a group called ETA, which begins to be closely investigated.

Three years later, during the longest strike of the Franco dictatorship, Txabi is elected leader of ETA. To assume his new role, he quits university and breaks up with his girlfriend.

To fund ETA's activities, Txabi and his comrades decide to rob a bank, adding pressure on Manzanas to secure an arrest. When Txabi's bombing plan goes wrong, Manzanas arrests and tortures his comrade.

Txabi loses a notebook of poems during an escape from the police; Manzanas becomes a target when ETA takes a vote on which Francoist leader to execute first.

Txabi and his companions are getting closer to crossing the invisible line by intensifying their activities and identifying possible targets.

Following the incident with Civil Guard Pardines, Txabi and Peru are stopped at a police checkpoint, where a shootout ensues and forever changes the course of history for both ETA and Inspector Manzanas.
