At first, a standard erotic thriller fare from the 90s, but with a few detais that makes it worth a watch: the fetishism, the great cast doing a great job, the loopy Bernardo Bonezzi score (which makes this film so close to Soderbergh's "Underneath") and a good following of the noir tropes. Very similar to "Entre las piernas", but all in all the erotic noir was actually very popular in Spain around the 90s (and quite interesting, and sadly mostly forgotten except "Amantes").
