A depraved sex killer preys on women of ill repute in the red light district area of Boston, Massachusetts. Hard-nosed maverick private detective Gunner Sloan (stolidly played by Dave Haller) gets hired by the wealthy Fairchild to find the psycho after the creep assaults Fairchild’s daughter Regina. While this movie suffers from flat direction by David W. Hanson, a plodding pace, and poor acting from a lame no-name cast, it nonetheless still manages to sustain the viewer’s interest thanks to the lurid subject matter, a sleazy narrative that combines a seedy film noir atmosphere with kinky giallo-type elements (the sicko likes to strangle his naked victims), a generous amount of tasty female nudity, and a few seamy soft-core sex scenes (the opening protracted interracial lesbian make-out session and a subsequent girl on girl set piece rate as the definite scorching hot highlights). The clumsily staged violence delivers several unintentional belly laughs. Moreover, the bevy of fine looking ladies keep this movie watchable: Ravishing redhead Sandy O’Hara, slender tanned fox Judith Lowe, busty luscious brunette Lee Sherry, and leggy blonde dish Toula Flambouris. With its wealth of static master shots and frequent use of queasy zoom-ins, John Hargrove’s plain cinematography provides an appropriately rough’n’ready visual aesthetic. The groovy score hits the swinging spot. Worth a watch for fans of low-grade grindhouse trash.
