On New Year's Eve, when every home is lit with reunion lights, a skyscraper in the city center hides a deadly secret. A so-called "Year-End Layoff" turns into a brutal Twelve Zodiac survival game. Finley Kirk, a low-level office worker, is only trying to earn money for his mother's treatment when he is trapped inside. There are no laws, only survival. No colleagues, only prey.Former bosses become monsters, and coworkers turn against each other as the corporate world collapses into chaos.

Owen Lane and his wife Evelyn Denton live an ordinary, tightly budgeted life, carrying a heavy mortgage every month. Evelyn's brother Mike Denton drifts from job to job, favored by their mother, and keeps finding reasons to ask his sister for money. Evelyn always gives in, and Owen swallows his frustration for the sake of peace, telling himself her loyalty to family is simply who she is. Then Owen wins the lottery, eight million after tax. It is enough to change their lives, but he says nothing to Evelyn at first. He is afraid of what her family will ask for once they know, and afraid of how far Evelyn might go to give it to them. The silence he keeps becomes its own kind of test.
