80 office workers are locked inside their building and told they have to kill 30 of their own…or else. Thus begins a showdown of paranoia, tension and violence. The heated moral discussions help space out the brutal acts, but there’s sufficient stress to keep them compelling (a strong cast helps). Basically, this is a grisly cat-and-mouse game with the audience guessing who’s next to go. It doesn’t break new ground for the genre, but the premise is original and the plentiful kills are sufficiently and skillfully dispatched.
