The Woods - first idea

A group of freinds visit a site of a brutal murder of which the murderer was never caught. One person of the group claims to see the people that have died. Stupidly, the group of friends decide to camp out at this sight. The person that claims to see the victims tells the story of what happened. "We'll all die out here." The malevolent spirit of the murderer (only seen by one character) starts to pick of the characters one by one. Leaving the last character to try and escape, but will they?
