Gallic helmer Abel Ferry (not to be confused with Abel Ferrara) helmed this French-language gorefest. A group of twenty-something friends undertake a mountain-climbing expedition to Croatia. Despite petty internal squabbles, a romantic rivalry, and one poor fellow's dire case of acrophobia, all goes as well as can be expected, until one of the climbers, Guillaume (Raphael Lenglet), makes the ignorant decision to chart an abandoned trail. Before long, the innocent travelers fall prey to the machinations of a crazed mountain butcher named Anton (Justin Blanckaert), including an oversized bear trap for humans and a spike-filled pit; when Anton learns of the climbers' presence on his mountain, full-fledged carnage ensues. As something of an in-joke, Anton's name literally translates as "to go into battle."
