When a werewolf kills a member of a camping group, one man must unite the group to resolve their differences and survive the night!

"?one man?" is far too vague for a MC description in a logline.

How does the death of a camper motivate people to unit? How are a group of people go camping together and not be united? What does "...resolve their differences?" look like? What differences?

The elements of the story are too vague and fail to exhibit a clear cause and effect relationship.

The stakes are life or death in nature this is clear but there have been so many stories where this is the case, what could make this one interesting is a personal stake. Could the dead camper be the MC's best friend, brother, wife, lover or business partner?

Hope this helps.
