A family of werewolf hunters are manipulated and systematically brought to the brink of extinction by those they hunt.

The juices are flowing guys, keep them coming, this is awesome! How do you feel regarding this update?

"Werewolf hunters are stalked by an Alpha, they discover it wants to eliminate them and add their daughter to it?s pack."

All very helpful, thank you. Ok manipulate is out. How about this, Werewolf hunters are stalked by an Alpha, they discover it wants to end their line, and add the last remaining member, their daughter, to it?s pack.

"A family of werewolf hunters are manipulated and systematically brought to the brink of extinction by those they hunt."

I like the concept. I agree with "manipulated" as being an odd choice of words, unless, in fact, they are manipulated as in "mind controlled" or something along those lines. If that's the case, it might behoove you to tell us HOW they are manipulated. If you mean tricked, stalked and slaughtered, those three verbs are probably better suited for a logline.

"The hunters become the hunted when a pack of ravenous werewolves chase down a wolf-killing team one-by-one..."

There's still an ending that needs to be developed. A good twist to a old classic.
