Bloodlust

Six hikers are trekking through the wilderness and make camp. Mark is awoken in the middle of the night and sees a wolf stalking them. When it attacks and kills one of the campers, Mark shoots the beast six times with his gun, but fails to kill it. The campers then realize that they're not dealing with any ordinary wolf. Throughout the night the werewolf picks them off one by one, and the survivors have to devise a plan to kill it before they all die.
