Overview

• The six-part series adapts Ramsey Campbell’s novel and extends Jaume Balagueró’s 1999 film into a standalone thriller.
• Creators Pau Freixas and Pol Cortecans build new storylines and characters to give the show its own identity apart from the original film.
• Miren Ibarguren stars as Dr. Claudia, whose daughter’s unexplained disappearance propels her into a journey through grief and supernatural phenomena.
• The production’s visual design draws on late 1960s and 1970s film techniques—grainy textures, zooms and moody lighting—to amplify its suspenseful tone.
• Ibarguren describes the role as emotionally intense, requiring rigorous preparation to detach from Claudia’s trauma after long days of filming.
