I have a friend that was involved in the film. Here are a few small leaks that I know.
Skull is not the real title, it's actually Hunter. Which was the original title for Predator.
The film takes place during the Comanche wars, when a small native village is invaded by American infantry. The people are murdered and some are kept as slaves.
The film initially is from the perspective of the infantry similar to the original film, except our lead character is a female warrior who is captured.
Near the half way point all the infantry are murdered. And she begins her own battle against the predator.
It's almost as if Dutch died and the female character became the lead.
The film is meant to be showing the brutality from all perspectives.
That's all I know. I've heard it's actually incredible. Relatively low budget. And it mirrors a lot of the original.
Ive also heard they are considering backing out of it being a streaming film, because there is confidence in a theatrical release.
