The Belko Experiment

"It at first seems to be an ordinary morning on the job for a group of Americans working for a not-for-profit in a modern office building in Colombia. After noticing that their Colombian colleagues have not arrived for work, office worker Mike (Gallagher Jr.) spots some unfamiliar security guards entering a large hangar nearby. Moments later, an icy voice comes over the building's PA system and calmly explains that the employees must kill a certain number of their co-workers — if not, they will be killed themselves. While the boss (Tony Goldwyn) tries to calm the troops, Mike belatedly realizes that something truly sinister is going on — and when metal doors come sliding down on all the building's exits and windows, it becomes clear that friends and colleagues are now suddenly enemies in a bloody and brutal battle to the death."
