Manuela Velasco portrays Ángela, a television reporter who, alongside cameraman Pablo Rosso, is working on a piece about firefighters. When they respond to an emergency call, the pair join the fire crews, only to discover a frightening situation where being trapped isn't their biggest concern as a rapidly spreading fire reveals something else entirely – something that seems driven by an insatiable need. The film adopts a camera-centric viewpoint reminiscent of "Blair Witch" (1999), and that’s when I started to lose my focus. While the dark, twisting hallways of the large apartment building are effectively captured through intense visuals for roughly ten minutes, afterward, what felt like exaggerated performances, constant screaming, and an excessive amount of ketchup just suggested a lack of resources or creativity in producing something truly distinct or noteworthy. Velasco succeeds if her goal was to make viewers strongly dislike her character; I would have been glad to offer her up to the danger if I were one of the firefighters attempting to rescue people while dealing with her increasingly irritating behavior. It moves at a brisk pace, but even within its eighty-minute length, I found myself tired of the repetitive nature of it all. This just wasn’t for me, unfortunately.
