Eind jaren 90 vormen Sagrario, Paz, Gloria en pater Girón een onderzoeksteam dat gespecialiseerd is in paranormale verschijnselen. Hoewel het niet uitstekend gaat met de groep, stemmen ze ermee in een antiekwinkel te onderzoeken waar vreemde dingen gebeuren. Maar wat een zaak als alle andere leek, wordt de moeilijkste van hun leven. En alleen samen zullen ze het kunnen oplossen.
