Five kids run out of gas in a snorwstorm and take shelter in an empty building, and things fall apart after one turns up dead. Thriller plays like a horror movie before veering off into a procedural; an unfortunate move, because it was a mediocre horror movie, and then a passable thriller, but the break in momentum in what had been a horror movie with much too long of forward-flashing from the action in the school to police interviews with the survivors kills it. Eventually it gets interesting as what actually happens is revealed, but halfway through the third act is way too late for a movie to start to get interesting.
