Well shot Spanish mystery horror with elements of a slasher and action movie: drugdealers, ancient witchcraft and mysterious eclipse converge in modern Madrid and create a nice atmospheric mix, a little condensed ending but the matter is rather on a small budget, the actors especially Ester Expósito main character and Magüi Mira played very well but the rest of the cast also tried. Special effects are certainly not outstanding but not the worst of them, interesting finds in the form of interpretation of the magical guardian. The creators gave as much as they could and it turned out very well, I recommend giving a chance.
