The official premise reads:
"After a Black Friday riot ends in tragedy, a mysterious serial killer, known only as John Carver, comes to Plymouth, Massachusetts, with the intention of creating a Thanksgiving carving board out of the town's inhabitants."
The movie is actually based on a fake trailer that Roth made for 2007's Grindhouse. It proved so popular that he eventually decided to develop a real movie based upon it.
"The R-rated cut has everything I want. So you can always add more gore, but I don’t feel stifled in any way, it’s the far end of the hard-R spectrum, so what you’re going to see in the theaters is my director’s cut," Roth told SFX Magazine.
"The kills have to be incredibly satisfying. It has to be really scary and really fun. We’ve had a couple of screenings where there’s screams, applause, cheers, people thinking we’ve gone too far…"
Roth also explained why it was necessary to trump what people saw in the original fake trailer.
"Every time you do one of those kills that you shot before, it has to be as good or better, because otherwise, what’s the point?" he continued.
"I don’t want people to watch and go, 'It’s better in the trailer.' So if you couldn’t top what we did in the trailer, you had to do something different. Part of the fun was it freed us up to come up with all-new kills."
