[Miss Olivia]

Okay, there is this movie I saw when I was a kid, and I'm sure that's the way half of these WHAT WAS IT threads start....anyway, I remember it was about some kind of doorway and there was a girl and two guys, and one of the guys got all his hair sucked off or something by a monster he was unconcious and bald for a while, and the girl got possessed and turned into a slut for a little while, and one of the guys was eaten by bees or bugs of some type and he was lying in the floor mostly eaten with guts and stuff hanging out....I seem to remember a lot of slime.....I'm sorry it's so vague, but I was very young when I saw it, and it's been in the back of my head for about twenty years and I think about it once in a while....any possible ideas?
