She Walks in Darkness

The plot follows Amaia, a Guardia Civil agent going undercover for years within the ETA ranks seeking to crack the location of the group's multiple weapons caches (zulos [eu]) scattered in southern France.^[1]

Written by Agustín Díaz Yanes, the premise of She Walks in Darkness is similar to Arantxa Echevarría's Undercover (2024), which wrapped shooting some weeks before the intended beginning of the filming of She Walks in Darkness, although Echevarría's film follows closer the biography of Elena Tejada, while Díaz Yanes' film is more of an amalgam of stories of multiple Spanish law enforcement agents.^[4] The greenlight of a second film under such circumstances is not usual in Spanish cinema.^[4] Shooting locations included Gipuzkoa and Iparralde.^[5] The film is a Basoilarraren Filmak production.^[6] Paco Femenía [es] worked as cinematographer.^[7]

The film was presented at the 73rd San Sebastián International Film Festival on 24 September 2025.^[8][9] It received a theatrical release in Spain on 3 October 2025 by Tripictures, followed by a streaming release on Netflix on 17 October 2025.^[10][11][12]

Luis Martínez of El Mundo rated the film 4 out of 5 stars, considering that, just like Undercover, it is an excellent story perfectly coherent with its intentions.^[13]

Harri X. Fernández of Deia lamented that the characterisation of all the characters drawn by Díaz Yanes, starting by Abaitua's, is "one-dimensional", while pointing out that the film does not work as a thriller either as it "lacks tension and pace".^[14]

Alfonso Rivera of Cineuropa billed the film as "a gripping thriller of imposture, espionage and lies", sometimes feeling "like a horror flick, such is the anguish and tension of its scenes".^[6]
