I remember watching this in the late '80s. A group out in the wilderness (possibly couples), being stalked or with a sadistic type of leader. The scene that sticks in my mind: The group encounters a dead animal (a bird I think) and a woman is coerced by her husband or boyfriend to strip and dance like a native around said bird. She is fully nude and he cheers it on while taking pictures (I think) and she appears humiliated while the others look disgusted.
I'm pretty sure it's a Canadian flick. Don't think it's DEATH WEEKEND, although I haven't seen it.
Can anyone help?
