[4] Olga Vasilyeva, a young woman raised in an orphanage and studying at a vocational school, is determined to find the mother she has never met.
Olga, kind-hearted, straightforward, and resilient, often speaks her mind, which creates tension with Elena’s daughters, Anna and Galina, who are spoiled and disdainful toward the provincial newcomer.
Olga’s bluntness also inadvertently stirs conflict between Elena and her husband, Vadim Antonovich, who has been struggling with stalled ambitions in academia.
When the vacation ends, Olga returns to her vocational school dormitory at the Ural Heavy Machinery Plant in Sverdlovsk.
Eventually, she receives news from Elena: Vadim Antonovich has found her mother in the town of Toropets, in the Kalinin region.
