An emergency call comes into corporate headquarters from an isolated medical research facility: "We are under attack " then the line goes dead.
A corporate security team, composed of former special operations soldiers, is deployed to investigate to them. It's just another recon mission-until they arrive and make a gruesome discovery: The staff's severed heads impaled on the perimeter fence posts.

One sees an opportunity to annihilate the other-and the team is trapped in the middle and that is only the beginning of their problems.
