Spanish film that has horror and thriller. It is a proud B-Class (that color and "spots" in the image), and that is clearly a tribute to that type of cinema. The plot is not original at all, and I don't know if it is appropriate for the characters to be the way they are, especially the protagonist, who does not have time to digest anything very well due to how short and fast it is, although, nevertheless, that it's a blessing! You can see the precariousness in many scenes despite the fact that the director manages to make them work, but the best thing is the music and the interpretations of the three protagonists. Almost between a Hammer Film and William Castle movie.
