The plot: For the workers of Belko Industries, situated in
an office building in Bogotá, it started out like any other work day. That is,
until a mysterious voice rings out through the building posing a terrible
ultimatum. All the doors have been locked down, and every window has been
shuttered; the workers are trapped inside. The mysterious voice tells them
that, of the 80 workers in the building, 30 must be killed in order for the rest to make it out alive. If not, 60 of them
will be randomly selected to die instead. With their options running out and
tensions running high, it seems that some are more willing to play along than
others.
