Karen the Beauty Queen Butcher.
I don’t know where to begin because I don’t know what’s real and what isn’t.
Here’s the premise:
Karen an unhappy married woman joins several Beauty Contests in the hope of being famous and adored by complete strangers. As she continues to lose beauty contests, we see that her competition is being killed off one by one. As we follow Karen’s journey through the film we discover who is the killer and what are the true motivations behind the murders.
The actual murders look like cartoons. (You get the idea from the trailer.)
I don’t want to waste any more time on this. Here’s a review from Horror Central that sums up the film well.
The nudity is from a woman named Knives Suicide. I didn’t make that up. Here are the credits.

IMDb calls her Suicide Knives, but that is wrong. She is really called Knives Suicide, and she is not AI like Tilly Norwood, but a real person profiled here, with several additional links on the bottom of that article.
So here’s Knives in the flesh:
This video is a raw, unedited capture. For the screen shots above, I removed the amber filter.

Just buckets and buckets of ‘why’?
