There was this foreign movie, maybe in German or in Portuguese, where a guy picks up a lady on the side of the street then takes her back to a hotel room with him. They take a bath together, almost has sex, then he says something that sets her off and she gets out of the tub and goes into the hotel hallway while wearing nothing. She gets into an elevator, then goes to a phone to dial a number, then while she’s in the middle of the call, a few guys come and pick her up (while still nude) and carry her to their hotel room and throw her on the bed.

The movie seemed to be made in the 80s or 90s.
