I had thought this was going to be along the lines of HOSTEL or SAW, and was pleasantly surprised when it turned out to be more an adventure/thriller movie than anything else. A group of tourists narrowly escape death on a bus when it goes over a cliff, only to become targets by a local Brazilian doctor who wants to harvest their organs. This guy is nuts. There are a few gory scenes, the script and acting are strong and it's an entertaining movie.
