Made for tv? Seems like a made for tv movie.
One of the main girls was in a few episodes of Supernatural. My favorite show.
Four friends go out looking for a mysterious lost city and, of course, they find it. Unfortunately for them, its also sacrifice time and they are looking mighty tasty.
Its not even on IMDB...anyway, its a lot like M. Night's The Village. They are trapped in a long ago time, only this one has much more fantasy involved.
Do I recommend it? Not really. There was nothing else on tv...
