Netflix recently unveiled the poster and the trailer of the Spanish political thriller, She Walks in Darkness, directed by Agustin Diaz Yanes. The film (its original Spanish title is Un fantasma en la batalla) follows the life story of Amaia, a young Guardia Civil officer, who spends years undercover within the armed group, ETA. Her risky assignment is to trace the concealed weaponry smuggled across the border in southern France.
She Walks in Darkness is among the major Spanish-language Netflix releases of the fall and early glances already give away the tone. The trailer presents a dark and tense mood and puts an emphasis on intense character moments instead of glitzy action. Netflix makes it plain that this is no light detective story, but a heavy, slow drama about infiltration, loyalty, and the great dangers of the real world conflict.
She Walks in Darkness: Release date and where to watch
She Walks in Darkness will be released in Spain on October 3, 2025 and will be available online on Netflix on October 17, 2025. This is to allow the European fans to watch it on the big screen a bit earlier. The film will first debut at the 73rd San Sebastián International Film Festival in September, which is an ideal venue to release a Spanish political thriller.
Trailer and poster have already been released by Netflix, featuring the somber Basque scenery, gloomy interiors, and a chilling plot revolving around an undercover existence that gradually consumes a person.
Cast and crew
She Walks in Darkness has a strong Spanish cast headed by a powerful actress Susana Abaitua, who plays the role of Amaia, the undercover agent. She is supported by Andrés Gertrudix, Iraia Elias, Raul Arevalo and long time actress Ariadna Gil.
There is a powerful Spanish production unit in the background. It is directed and written by Agustin Diaz Yanes, and features popular producers Belen Atienza, Sandra Hermida, and Juan Antonio Bayona, a lineup that signals that Netflix is after quality and mass appeal.
What to expect
The film belongs to the emerging trend in Spanish cinema: political thrillers that are real and take a close look at recent history through personal accounts. She Walks in Darkness is not a movie about big action sequences. Rather, it is concerned with the emotional cost of living a dual existence, where identities become confused, ties are stretched and white lies grow to become major problems.
The cinematography visible in the trailer and poster, is dark and moody. One should anticipate lots of darkness and rough coastal and village scenes and intimate shots that keep the audience familiar with Amaia’s thoughts. The film relies on good acting and tension that builds as opposed to rapid action.
The story is set in the Basque Country and southern France and the infiltration of ETA cells provides it with a tense and realistic advantage. It does not provide simple heroes and villains. Rather, it challenges you to consider the grey-area decisions people have to make.
She Walks in Darkness is an ideal October watch in case you are a fan of slow-burn spy thrillers where characters and suspense take center stage over the explosions.
