Barricade (2007 )

Nina is visiting her longtime friend Michael and his pal David in Germany for a much needed vacation. The trio decides that, to get their mind off their day-to-day lives, a camping trip into the nearby Black Forest will do them all well. Little do they know, a clan of bloodthirsty ghouls also calls this area of the woods their home - and they don't take kindly to strangers impeding on their land. As the bodies begin piling up, the friends' innocent vacation becomes a horrific battle for survival. The cannibalistic monsters know the forest better than anyone... and their victims are in for the fight of their lives.
