"When Paris is submerged in a strange mortal fog, survivors take refuge on the city's upper floors and rooftops. Without news, electricity, water or food, one small family struggles to survive the catastrophe. But as the hours pass, they are forced to face reality: rescue teams aren't coming. If they hope to make it out alive, they will have to risk going out into the fog."--Container.
