Derek Cho receives a pink slip at work after being framed by a co-worker. He refuses to leave until he can make his case during an appeal hearing. If he had only agreed to leave, he might have made it out in time:
That same day, the spread of a dangerous airborne virus results in a full lock-down quarantine. The virus causes people to act on their worst impulses.
After the virus spreads everywhere, one of the head honchos takes a hit out on Derek for several hundred thousand dollars.
Derek must fight brutally against his co-workers to stay alive.
