High Frontier

Mateusz, an ex border patrol guard, revisits his old stomping ground, a remote station in the wilderness of snowbound mountains between Poland and the Ukraine, as a bonding experience with his two teenage sons after a family tragedy. As they get to the isolated cabin station, a stranger collapses half frozen onto their doorstep mumbling something about a lost party of people. Mateusz decides to set off in the snow to find the group, leaving the boys to care for the stranger. However, after regaining consciousness, this stranger appears not to be the victim of chance as he seemed at first, and the family holiday is transformed into a terrifying hellish experience.
