Nothing Underneath (1985)
The plot of "Nothing Underneath" required some attention but it was worth it. Someone wearing black gloves was bumping off 80s fashion models with a pair of scissors and Donald Pleasence (as an Italian cop) and a forest ranger had to work out who it was. Boobs, bush, blood, lezzing and modeling to "One Night in Bangkok" were featured and the power drill climax was very exciting. The killer was a psycho lesbian with big 80s hair who jumped out a window with her dead girlfriend. The dead girlfriend (whom she'd murdered) was the twin sister of the forest ranger and they shared a psychic link. Like I said it required attention. Suspension of disbelief came in pretty handy too.
