In the early 90s I saw a film at a friends house. I dont really remember the plot but I think it took place in the american southwest and involved a road trip. I have a feeling the film was made in the late 70s or the 80s. I vaguely remember a man, or possibly two men, travelling in a station wagon or other large car with a blonde. At one point there is a scene where the girl is holding a gun at the guys head and I remember her makeup being dark and heavy especially around the eyes. I think drugs were involved. At another point I think they stopped by a lake or waterfall. Anyone have any ideas. I dont think I can provide any more details. Just wanted to throw this our there. I appreciate any responses. Thank you.
