This re post contains more detail than the original however no further plot elements are introduced and as such this sentence is vague in its meaning.

For clarity I must ask, is this intended to be a logline or a statement of sorts related to a story?

Check out the definition of a log line and its components here:
https://loglines.org/howto/

To help with the construct here are a few key questions that are best answered prior to drafting a logline:

Who is the story about?

What does he or she want?

How will he or she achieve it?

Hope this helps.

The logline structure needs adjustment in a way that brings the inciting incident in sooner preferable first in the read.

For example:
When a pack of ghouls attack her town a sheriff must fight the beasts to protect the people.

The reason for the ghouls attacking the town is less important as it is not part of the story reserve that for the synopsis. The sheriff’s fight to save her people is what the story is about.

Only question I have is will there be any danger to the town from a pack of ghouls if what they are after are dead bodies?

I think that as a western horror movie the concept is good and needs little explaining to create interest therefor the logline can be as lean as the example above. That said its always a good thing to flesh out an idea with layered character elements.

Is there a personal stake at hand for the sheriff?
What is her flaw?

If you could add these into the logline it would be a great logline for a western horror film.

Hope this helps.
