Alfred and Julia live in a land of pure invention. It is the richest and most beautiful land in the world. From a height, this land looks like a piece of felt. Alfred and Julia have been married for 8 years, are childless, and live on the 16th floor of a new building. Thanks to their various crises, they have got to know each other somewhat better, but their most outstanding characteristic remains their mediocrity. On Friday, August 12th 1977, a mysterious epidemic breaks out in their country. The mass media ensure that the news is widely broadcast. The authorities order a ban on information, but those concerned break their imposed silence.
