I could be faaaar off, but the trailer makes it look like it's a supernatural take on the racial violence that occured during Jim Crow. The "dance with the devil" and then the ominous shots of Hailee Steinfeld, and we know that entertaining, merely looking at a White woman back then led to destruction of Black communities. I wouldn't put it past Coogler to do that lol.
They will reveal more close to release I guess, maybe in another trailer. I'm fine with this though, this is what trailers are supposed to do. Pique your interest, while still playing close to the chest. The first Alien trailer showed practically nothing at all and it was still effective.
