Another workplace horror movie, similar to Mayhem.
Shortly after starting their work day at the Belko Industries in Bogotá, Colombia, the building goes into lockdown and the employees are informed that they must start killing their fellow co-workers or a number of random employees will be killed with a little explosive charge implanted in the backs of their necks.
Initially, the employees try to avoid killing each other until it is clear that they have no choice. That’s when the carnage starts, and boy does it paint the walls red.
The movie has a great cast including John C. McGinley, Tony Goldwyn, and Michael Rooker, but none of them are used in any satisfactory way.
The big reveal at the end was also a bit of a let down, which then cliffhangs a wide open ending that leaves you scratching your beard.
