In this prescient thriller about an all-too-possible scenario, a man fights to keep his family alive when a cyberworld meltdown and fierce storms cut New York City off from the world.

Mike Mitchell is an average New Yorker living in an apartment in Chelsea, struggling to keep his family together. When the Internet goes down, he suddenly finds himself fighting just to keep them alive. The electricity and power supplies fade in and out, and the explanations offered by the authorities are vague and untrustworthy.

A string of increasingly bizarre disasters starts appearing on the world's news networks, and a monster snowstorm hits New York City before Christmas. Mike and his close friends and family hunker down in their apartment building for safety, organizing and rationing food and water. Outside, the boundaries between lawful and criminal behaviour break down as resources become scarce. With the threat to their safety growing, Mike and his family pin their hopes on fleeing the city for the countryside.

But as the world and cyberworld come crashing down, New York is suddenly cut off, turning the city into a wintry tomb where nothing is what it seems, and where no one can be trusted . . .
