The lakeside resort is visited by a writer (Henry Gregor) dedicated to a thriller. He hides in his room writing, noticing that Veronica is more than a little odd. She tirelessly produces impeccable ceramic sculptures, adorning the hotel. He hears her talking to herself, witnessing her hostility every time a couple rents a room. Veronica is a kind of female Norman Bates, a timid, isolated woman fearful of men and resentful of unmarried couples who don’t inform the motel that they are love-struck and on the brink of a breakdown. One night, two hikers (Antonio the Mayan and Isabel No) are hacked to death in their room. This is shot from the perspective of a black-gloved, razor-wielding killer. It remains unclear whether Klimovsky is imitating or parodying the popular Italian giallo of the time. Bloodshed is certainly abundant, with close-ups of razor cuts through necks, faces, and chests. Later, a vulgar businessman (Ricardo Merino) is killed after an intimate encounter with a prostitute. Again, we get close-ups of black gloves, but once more, we do not see the killer's face. Is Veronica, or Veronica's "dead" husband, returning from the grave? The ironically satisfying double twist endings reveal the truth.
