Leonid Sednev, imperial chimney sweep and later kitchen help, was fifteen years old on the night of the 17th July 1918, when a group of soldiers of the Bolshevik Revolution brutally murdered the Russian imperial family. Leonid was the only survivor and invisible witness to the tragedy. Much later, a now very old Leonid decides to piece together his memories and begins this story in which he recreates the last years of the Russian Empire and the change of regime. Carmen Posadas brings us her usual mastery through the eyes of a servant, in the fascinating world of the imperial family: lights and shadows of the palace, while princesses and chimney sweeps, tsars and Bolsheviks, luxury and poverty file by.
