Written by the prolific Ernesto Gastaldi (TORSO), infused with a seductive Ennio Morricone score and featuring a memorable turn by Nieves Navarro a.k.a. Susan Scott (DEATH WALKS AT MIDNIGHT), this is a trippy giallo delight that brings together the talents of many of the genre's leading lights on both sides of the camera.
Before the influence of Argento's THE BIRD WITH THE CRYSTAL PLUMAGE permeated every corner of the genre, another strain of these distinctive Italian thrillers enjoyed considerable success. These ''melodrama gialli'', heavily inspired by Clouzot's LES DIABOLIQUES, relied less on graphic violence / high body counts and more on psychological tension.
Minou leads a pampered, dull life with her frequently absent husband Peter. While out walking on the beach one night, she's accosted by a mysterious blackmailer informing her Peter is a murderer. Driven by misplaced loyalty to her husband, Minou gives in to the blackmailer's perverted whims in exchange for his silence. As the blackmailer ups the ante, can Minou hold on to what little remains of her sanity?!
