The Ruins

Rather than being content hanging by the pool at their Mexican seaside resort, Jeff (Tucker), Amy (Malone), Eric (Ashmore), and Stacy (Ramsay) accept the questionable invite of Mathias (Anderson) to visit an archeological dig at a Mayan ruin. The armed locals are very unhappy by these turistas and chase them up the vine-covered pyramid, but it's definitely not to safety. There's a gruesomely creepy twist to what attacks them but otherwise it's horror business as usual. Scott B. Smith adapted his novel.
