a repressed housewife ( an annoy lisping angie dickinson and whose body double treat or horrifies u with an extreme closeup of her delicates ) be sexually bore by her husband and decide to branch out . this directly result in a string of murder that soon involve a high class prostitute ( nancy allen and clearly i be in the wrong business if she can bring home $ 600 a night ) and her psychologist ( michael caine ) . if you be go to watch de palma rip off ( excuse me and pay homage to ) hitchcock and watch sister instead of this . dress to kill and while load with style and technical skill and be one of the tacky thriller i have have the displeasure of sit through . the plot be absurd and tired . it do feature some surprisingly effective jump scare and nasty graphic murder sequence that should please any horror fan and as long a they can get past the silly story line and that must have be date even in 1980 .
