Fine Drama Thriller about Spain vs. the Basque Separatist organization ETA during
the 1990's, and the last years when the ETA used violence towards the Spanish state
in their quest for a "liberated" Basque Country.
The Spanish police (and the Special Force) tried to infiltrate ETA by planting moles
and in this film young police woman Mónica Marin AKA Arantxa (Carolina Yuste)
moves to San Sebastian many years before she's assigned a task by ETA members.

I remember visiting San Sebastian in the summer of 1975 (yes, i'm an old guy) as a
teenager and there were soldiers armed with automatic guns everywhere, at every
corner almost and the Generalissimo Franco died later that year.
Then it was a War between between Fascist Spain and ETA which explains the very
grim and scary Spanish soldiers when crossing the frontier from and to France.

The Film:

A newly graduated and young female cop, Mónica Marín is picked by her boss,
Chief Inspector Ángel Salcedo (Luis Tosar) to be an undercover cop and infiltrate
the ETA. She lives for seven years in the 1990's and works and meet her Basque
friends before she's trusted enough by the ETA leaders (the very few of them left)
to make contact with an ETA "soldier".

She's to share her apartment with him, Kepa (Iñigo Gastesi) until he's ordered to act.
Ángel and his task force have her apartment under surveillance and listens to
everything they say. Then, another ETA "soldier" Sergio (Diego Anido) joins them,
and he's suspicious of her and scary as hell. Will her cover hold?
ETA announces a permanent ceasefire and Ángel's bosses orders the whole
Operation to be cancelled, but a few ETA loose cannons is not to be trusted.

Spain has had, and has, "problems" with Separatist sentiments expressed in some
of the regions/autonomous communities, as the Catalan Independence Movement,
The Basque and in Galicia and surely some more.
I visited Barcelona and Vigo in 2019 during the Unrest. In Barcelona people were
out in the streets protesting and lots of windows had Catalan flags hanging from
them, and some Spanish flags. Did people support independence then ?
In Vigo, Galicia, I only saw a very small Demonstration and mostly Spanish flags
were hanging from the windows, only a few Galician flags. Galicia stayed calm.
