Zhivago returns to Moscow and learns his wife, son, and father-in-law were deported and their location is unknown. Several years later, while sitting in a café, he sees a young boy who reminds him of himself as a child passing on the street with his mother, who he realizes is Lara. Before he can reach the pair, he suffers a fatal heart attack. Lara brings young Yuri to view his father's body, and as the two near their home, she realizes that the NKVD is waiting to place her under arrest. Pretending they're playing a game, she urges her son to run away as quickly as he can, with the book of poems Zhivago wrote over the years, before she surrenders to the authorities.
