In a world after the nuclear apocalypse a scholar helps a small group of children and adults survive, staying with them in the basement of the former museum of history. In his mind he writes letters to his son — though it is obvious that they will never be read.

It is the future, the world is in ruins and a large portion of the population consists of deformed mutants living in reservations. In this world a man decides to spend his vacation visiting the ruins of a museum that is now buried under the sea.

The protagonist finds out that some children were left behind in a sinking school, and is slowly driven mad as he tries to save them. A parable on the theme of the Last Judgment, numerous catastrophic events reveal a certain ambiguity in their origins, accompanied by the terrible suspicion that the things going on are some kind of a performance or theatrical production.
