Severance (2007)

Synopsis
When the president of a high-profile international-arms supplier takes his six best employees to an Eastern European mountain retreat as a means of rewarding them for all of their hard work, their team-building getaway turns into a life-or-death game of kill or be killed in Creep director Christopher Smith's suspenseful comedy thriller. Palisade Defense isn't just the leading supplier of weaponry for the war on terror, it's a company that truly cares about its employees. When the Palisade Defense's European sales division exceeds expectations, the president decides that his dedicated employees deserve a relaxing, corporate team-building retreat. The trip takes a turn for the worst, however, when a deadly enemy infiltrates the retreat with the singular goal of ensuring that no one gets out alive. ~ Jason Buchanan, All Movie Guide
