Trippin'(2011)

What happens when good buds go bad...

A group of three friends head to a cabin in the woods for the weekend. On their way they discover an arm in the road, blood coming from something wrapped in the back of a truck, and other strange things that unfold before their eyes. They plan on a weekend of partying, boozing, drugs and sex. Of course there is a campfire tale of a killer in the woods, the kids get split up, and the blood starts to flow.
