Exactly what it says on the tin, this is a Wrong Turn style horror thriller about cocky friends ending up as fish out of water in someone else's territory. And it's good, atmospheric territory to be lost in. The underground network is crumbling and filthy, the bad guys are deranged and frightening, and there are twists that are good (although you'll be expecting them if you've watched enough horror films). Even for a veteran, this is a fun film to enjoy.
