The premiere is a sold-out event, with film enthusiasts and locals gathering to experience the rediscovered masterpiece. As the film screens, the audience is transported to a world of surreal landscapes, industrial soundscapes, and haunting narratives.

As she delves deeper into the archives, Laura uncovers a series of cryptic letters and notes from Adrián Argüelles, detailing his obsession with the concept of "eclipses" – moments in time where reality and fiction blur. The letters hint at a larger, unfinished project, a feature film that would explore the intersection of reality and cinema.

As she unlocks the door, she discovers a room filled with dusty film reels, old scripts, and forgotten documents. Among the reels, she finds a peculiar one labeled " Proyecto Eclipses" (Project Eclipses). Intrigued, Laura decides to screen the film.

The story concludes with Laura, now an established film scholar, returning to the archives, searching for the next lost reel, the next hidden story waiting to be uncovered. The cryptic key, now a symbol of her journey, remains on her desk, a reminder of the secrets that lie hidden in the shadows of Cine Matadero Oviedo.

As they piece together the fragments of Proyecto Eclipses, they realize that the film was meant to be a reflection of Oviedo's transformation, a city caught between tradition and modernity. The film's narrative weaves together fragments of reality, blurring the lines between documentary and fiction.

The film turns out to be a surrealist experimental short film from the 1920s, directed by a reclusive Oviedo filmmaker, Adrián Argüelles. As Laura watches the film, she becomes mesmerized by its dreamlike sequences and the haunting narrative.

As Laura digs deeper, she enlists the help of the cinema's projectionist, Vicente, and together they begin to unravel the mystery of Adrián Argüelles and his lost project. They discover that Argüelles was a pioneer of experimental cinema in Oviedo, and his work was heavily influenced by the city's industrial and cultural heritage.
