A stubborn, inquisitive anthropologist believes an unidentified body found by the NYC police is a Neanderthal, but her investigation is quickly and ruthlessly suppressed by a secretive organization with links to the ultra-rich.

Great logline. But a couple of comments...

Would like to know how the anthropologist is connected to the NYPD. Was she hired by? Is she working with an NYPD detective?

Stubborn and inquisitive are good descriptors but don't seem to carry any weight. Are anthropologists normally apathetic and lethargic? Is he/she stubborn and inquisitive in face of the disinterest of the NYPD? What is the character contrast that will create conflict in the story?

Don't like the word quickly in this context. Doesn't add anything to it. I think it still reads well with: "...her investigation is ruthlessly suppressed by..."

Nice job, though.
