Also known as: Sex Psycho, The Demon in Miss Jones

Description: Beneath the respectable appearance of suburban married life lies a nightmarish world of infidelity, jealousy, and murderous obsession. Sex Psycho, also known as Widow Blue, follows a group of deeply dysfunctional lovers whose tangled relationships spiral into an increasingly grotesque nightmare.

Eva Blue is an unhappy housewife secretly involved with Nick, a married man whose neglected wife Elise has begun seeking affection elsewhere. Their complicated affairs become even more dangerous when Eva and Nick devise a deadly plan to eliminate Eva’s husband Jerry and seize control of his money.

Enlisting the help of Eva’s brother Marshall, the conspirators exploit Jerry’s attraction to men to lure him into a carefully arranged trap. What begins as an elaborate scheme of adultery and betrayal erupts into a shocking act of violence, transforming an ordinary suburban home into the setting for a grotesque criminal nightmare.

But murder is only the beginning. As the conspirators attempt to conceal their crime, their behavior becomes increasingly reckless and irrational. Sexual jealousy, forbidden relationships, and bizarre encounters push the story beyond conventional crime drama into deeply disturbing territory.

When Elise becomes entangled in the unfolding conspiracy, the situation descends into further confusion and brutal consequences. A final, dreamlike revelation leaves the audience questioning whether the horrifying events actually occurred or emerged from Eva’s troubled imagination.

Sex Psycho is an extraordinary collision of psychological horror, depraved suburban melodrama, and extreme sexploitation. Its explicit adult content, taboo subject matter, and sudden eruptions of gore make it one of the more unsettling curiosities of early-1970s underground cinema.

Legacy Note: Written and directed by Walt Davis, credited under the pseudonym David Stefans, Sex Psycho belongs to the particularly transgressive margins of American exploitation filmmaking. Its combination of domestic betrayal, sexual violence, and grotesque black comedy places it alongside the most uncompromising examples of the underground roughie tradition.

Susan Westcott portrays the manipulative Eva Blue, while Sandy Dempsey appears as Elise, the neglected wife caught in the murderous conspiracy. Director Walt Davis himself plays Jerry Blue, alongside Alex Elliot as Nick and Charles Lish as Marshall. Andy Bellamy, Rick Cassidy, and John Holmes contribute to the film’s unusually provocative ensemble.

Davis would continue exploring dangerous obsessions and violent moral hypocrisy in Evil Come Evil Go (1972), another remarkable cult feature in which religious fanaticism becomes a justification for murder. His earlier erotic drama Substitution (1970) offers another glimpse into the director’s unusual approach to low-budget adult storytelling.

Fans of the film’s performers can also discover Touch Me (1971), featuring both Sandy Dempsey and Andy Bellamy, in a different example of the uninhibited American sexploitation cinema of the period.

With its crude but effective photography, claustrophobic domestic settings, abrupt tonal shifts, and increasingly nightmarish situations, Sex Psycho creates an atmosphere of moral collapse in which almost every character becomes implicated in deception or violence.

Disturbing, excessive, and defiantly unconventional, Sex Psycho aka Widow Blue remains a fascinating piece of underground horror history—a sinister suburban nightmare where sexual jealousy turns murderous, respectability conceals depravity, and reality itself becomes impossible to trust.
