A classic and effective slasher flick from Norway, the Cold Prey franchise begins with a group of young, attractive friends on a snowboarding retreat. When one of them breaks a leg carving some sweet powder, they spot an old hotel they can use for shelter. The hotel has been abandoned since 1975 and is filled with ominous clues that the friends should not be there, down to a creepy message in the guest book from the hotel’s last visitors. But of course, this being a slasher movie, our young heroes remain unaware that they’re being watched… and that the snow will soon be stained red with their blood.
