Plot

A family fights to survive as the streets of Paris fill with a deadly gas.

A couple lives in Paris with their daughter, who suffers from an incurable disease that forces her to live in an hermetic glass bubble. One day, a mysterious fog begins to spread in the Parisian streets, killing everyone who gets caught in it. The parents find shelter on the roof above the mist, but the daughter is still in her bubble in the now fog-filled flat. Her parents must now cope with the lack of food, power, and information, but also find a way to get her out, since the bubble won't hold forever.

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 need to risk going out into the fog.

A strange, deadly mist envelops Paris. A group of survivors finds refuge on the upper floors of apartment blocks and on the roofs of the capital. With no information, electricity, food, or water, a couple attempts to survive this disaster and save their daughter. But as the hours go by, one thing becomes quite clear: there is no help on the way, and if they want to make it through this catastrophe alive, they will have to try their luck in the mist.
