Quick Answer
What is Demented about?

Demented is a 1980 American crime, horror, and thriller film directed by Arthur Jeffreys about a woman traumatized by gang rape who suffers psychological torment and is pushed to the edge when masked youths invade her home.

The SassyFlix Take

Demented doesn’t just tiptoe around exploitation—it stomps in, courtesy of a raw rape-and-revenge premise and a role for adult legend Harry Reems as the philandering husband. The film’s psychological angle delivers more than just cheap shocks, digging into trauma and paranoia in a way only early '80s grindhouse could.

Proof that not every Harry Reems role involves a pizza delivery.

Why Cult

Rape and Revenge Premise

This film dives into the brutal aftermath of sexual assault, following its protagonist from trauma to violent retribution.

Harry Reems in Mainstream

Adult cinema icon Harry Reems takes a rare non-porn role as the unfaithful husband, adding a notorious edge.

Psychological Horror

Demented explores the protagonist's descent into paranoia and terror, blending psychological horror with home-invasion tension.

Early '80s Grindhouse

With its 1980 release and R rating, this is pure grindhouse exploitation from the dawn of the slasher era.

Synopsis

A woman is gang-raped in a horse's stable, and even though the rapists are caught and imprisoned, she is harassed many moons later by ghastly visions of her tormentors, while her husband philanders and every little thing frightens her out of her wits.
