"Ten strangers, trapped beneath the Hudson River, are forced to depend on their fellow commuters in order to survive an apocalyptic event. Those left must fight their way through more than rubble to make it to safety. But the darkness is closing in, and with it their own individual fears and paranoia. It'll be a long road to the end of the tunnel . . . that is, if they don't kill each other before they get there."-- Provided by publisher.
