The last underground of V. I. Lenin - the safe apartment with M. V. Fofanova in the house number 1 on Serdobolskaya street in Leningrad (now - the museum-apartment of V. I. Lenin). MV Fofanova, who is a participant in historical events, talks (synchronously) about the preparation of her apartment for the arrival of Lenin, about the fulfillment of instructions from Vladimir Ilyich and NK Krupskaya, about his life and work in this apartment under conditions of the most brutal secrecy.
