The Woodland Killer

Teenagers decide to go on a camping trip in beautiful Norway, but little did they know that would be the last few days of their lives, thanks to Sven. Sven happens to be a paranoid schizophrenic. He has strange visions of his abusive father and he has to obey to avoid getting abused worse. He only does what he's told to:
1. To obey his abusive father.
2. Kill everyone who gets in his way.
Will everyone in his path die? Will they escape? Or possibly, will they be let go of being held hostage?
