A bevy of beautiful barmaids are getting picked off by a sadistic killer. As the cocktail waitress count goes down one by one, it’s up to a hard-nosed cop (William Smith) to stop the slaughter. Marketed as swinging sexploitation fun, The Swinging Barmaids is actually an eccentric proto-slasher, penned by frequent Roger Corman collaborator Charles B. Griffith, that’s packed with sleazy flare and excellent ‘70s footage of the valley.
