I was taken to see this unidentified movie as a small kid in the late ‘70s (I think; definitely not later than 1981). The scene I remember involved a man and a young woman alone in a sauna. I think they were strangers. He lifts her top up and, after an admiring pause, slaps her and grinds his foot into her face. Why I was in a theater watching this is beyond me, but of course we didn’t stay much longer. Sometime before we left, there was also some scene with the same (?) guy trying to drown some woman (?) in a fish tank/aquarium. Not surprisingly, these images stuck to my impressionable little mind, and at this point I’m very curious and looking for closure. Anyone know what movie this was? I don’t recall the actors, title excerpt, anything. Except that it was in theatrical release some 25 years ago.
