The protagonist of this dystopian YA novel is eighteen-year-old Romani boy Mojmír Demeter. He grew up in an orphanage and trained as a cook. Cooking is his passion and he dreams of his own restaurant. But things turn out differently. As a child, Mojmír would spend his summers in the mountains, in the cottage of his adoptive grandmother. Now the old woman is seriously ill but refuses to be hospitalized, she wants to die at home. Mojmír decides to leave Prague and to stay with her. While she is slowly dying he takes care of her, trying to alleviate her suffering as much as he can. Surrounded by pristine mountain landscapes, Mojmír does not know much about the horrible scenario unfolding in the cities around; about the rampant pandemic that is spreading rapidly: a mysterious, extremely contagious disease which particularly affects people living in large cities, under stress, under the influence of the media. The disease deprives them of their physical form, they just fade away.

When the food supply in the cottage runs out, Mojmír has to go to the nearby city, where he sees that everything has collapsed.
