Watch Skinwalkers (2006)

For them to live, we must die.

Skinwalkers — Fantasy, Action Film (2006)

Creatures, bound by the blood of the wolf, that can kill with curses and move at lightening speed, watching the night sky for the rise of the blood-red crescent moon. They are SKINWALKERS. They feed on our flesh and thirst for the taste of human blood. The red moon signals each pack, divided by principles, hell bent to survive an ancient prophecy.
