Elisa (Carmen Sevilla) is a high-class escort who witnesses new neighbor Miguel (Vicente Parra) disposing of the corpse of his wife, whom he's just murdered. Then he figures that she's better off being his accomplice rather than another victim, so he deeply involves her in the crime.
Much more of a drama / thriller than a horror film (although it can get pretty gory), "No One Heard the Scream" is ultimately an interesting look at two flawed but compelling characters, and their evolving relationship. Elisa, in particular, initially reacts to the crime as a normal, decent human would, but then reveals layers to her character: she's not exactly an innocent. And he's not the total creep you might expect him to be.
Full of philosophical musings toward the end as Elisa & Miguel ponder their relationship and their lives, "No One Heard the Scream" doesn't really dish out a lot of thrills, per se, but it can get pretty tense, and features some dark humor that could have made Hitchcock proud: at one point, Elisa & Miguel are traveling, arrive at the scene of an accident, and are asked to transport some victims to the hospital; naturally, they're very nervous when the police ask them to open the trunk!
The gorgeous Ms. Sevilla, and Mr. Parra (star of director Eloy de la Iglesias' breakthrough film, "Cannibal Man"), share good chemistry, and deliver thoroughly engaging performances. They are nicely supported by Antonio Casas, as one of Elisas' primary clients, Maria Asquerino, as Nuria, and Tony Isbert, as Elisas' hunky young "nephew" Toni.
What really sells the film, however, is the brilliant twist ending that the viewer may actually not see coming. It's just the icing on this particular cake, making this a solid Euro cult feature worth seeking out.
