But despite such promising potential, it is a much duller film to watch than it sounds in description. It very much wants to bill itself as a psycho-LSD film – tapping into the then burgeoning successes of both Psycho (1960)-inspired psycho-thrillers and the fad for LSD trip films following the success of Roger Corman’s The Trip (1967) – but in the end it is really never much more than a 1960s nudie film. Most of the time it consists of little more than scenes of girls taking their clothes off – indeed it very rarely consists of anything else. Strip scenes go on for sometimes 10 minutes at a time and the very first strip scene not long after the film begins consists of about 15 minutes of Susan Stewart gyrating in her underwear and clawing at her victim’s back, during which the camera coyly hides behind various objects in the warehouse.

There is really no plot at all – there’s a scene with a girl who undresses and has sex with the manager of the bar that goes on for another 5-7 minutes, yet contains absolutely nothing to do with anything else in the film. Occasionally the film cuts back to the two investigating detectives but nothing ever goes on there either. There are one or two interesting psychedelic trip scenes but these are few. It’s a fascinatingly lurid but hardly an interesting film.

Director William Rotsler is better known in sf fandom as a cartoonist and writer of various film and tv novelizations. During this era he sometimes had a secondary career as a director of nudie films.
