Sister Death (Spanish: Hermana Muerte) is a 2023 Spanish supernatural horror film directed by Paco Plaza, from a screenplay he co-wrote with Jorge Guerricaechevarría. A prequel to Plaza’s 2017 film Verónica, it follows young novice Narcisa (Aria Bedmar) as she arrives at a former convent turned girls’ school in 1940s Spain and uncovers the dark secrets haunting it. The film world-premiered as the opening film of the 56th Sitges Film Festival on October 5, 2023, and began streaming on Netflix on October 27, 2023.

Who Composed the Sister Death Score
The original score is by Spanish composer Mikel Salas, who previously scored [REC] 3: Genesis. Salas’s score for the 91-minute film leans into the atmosphere of its 1940s convent setting, and the movie leans on just two licensed needle-drops rather than a large soundtrack album.
Sister Death Soundtrack: Songs
| Song | Artist | Where It Plays |
| Tengo Una Debilidad | Antonio Machín | Plays from a radio during an interior convent scene, around the 32-minute mark |
| Maldito Duende | Héroes del Silencio | Scores the film’s final moments and end credits, around the 1-hour-23-minute mark, tying into the setup for Verónica (2017) |
Separately, the film’s promotional trailer uses the track “Kyrie Eleison” by Parry Music — a trailer-only cue that is not part of the film’s own in-story soundtrack.
