A well-known civil servant from the Mayor's Office in a provincial Russian town receives a note: You'll soon die. He takes no notice, and gets ready for his normal Sunday – family problems, his personal life, work, other matters… But this Sunday turns out very far from normal.  From the very start things come crashing down, smiting everything in its path, including all plans, external composure, and even his own life.

Sunday

Colleagues at work - Anna Sergeevna and young Lena - come to rest in a country sanatorium and become unwitting witnesses to the crime. They begin their dangerous investigation and feel that they, too, are in trouble. Trouble is everywhere here, everything around is saturated with it. Danger weakens and excites. Everyone is infected with danger, including the main suspect - Georgiy.
