Don't Answer the Phone! (1980) 

A deeply disturbed photographer and Vietnam veteran, named Kirk 

Smith, terrorizes Los Angeles by going around strangling 

lingerie-clad young women in their homes while taunting 

Lindsay Gale, a young psychologist, by calling her on a radio 

call-in show to describe his sexual hang-ups and misogynistic 

ways, while a local police detective, Lt. McCable, is always 

two steps behind in trying to catch the psycho.  (IMDB Matthew Patay)
