A group of college graduate friends meet up in Scotland for a holiday and encounter not only a vicious prehistoric bird that feeds on humans but the weird town that's been feeding the species. They've been feeding them out-of-twners so all of the friends are in danger. The majority of the movie takes place outside or in their rented camper.
Its an interesting idea, though the computer graphics of the creature aren't so convicing. I think they had "Q: THE WINGED SERPENT" in mind, but it pales in comparison to that monster.
