dark bar (1989)

elizabeth calls her sister anna to leave a message for her: she is going on a date with mark, at the dark bar. anna is drying her hair with a hair dryer and does not hear the ringing of the device. elizabeth (to whom a suitcase containing a red raincoat was delivered) is found dead in the room. it is from here that the sister begins investigations to find an explanation for a crime that apparently makes no sense.
