Silver Letters

December 1916. Petrograd. Olga Laricheva and Sergey Gorchakov love each other, but due to a random quarrel, the whimsical beauty Olga, spitefully, marries her admirer Nikolai, whom her younger sister, modest Ksenia, loves.
A world full of chaos: the red autumn of 1917, the grim thirties, and the blockade of Leningrad will ultimately separate the heroes onto different paths, but fate will complete a full circle, and its silver threads-letters will carry echoes from distant years to our days, finally freeing the ghosts of the past from given promises and oaths.
