...Your Daughter Alexandra(1986)

ΩSixteen-year-old Alexandra was raised without a father. One day, while her mother was away on a business trip, she found an old letter addressed to Mikhail Maximov. Deciding that this was her father’s name, the girl looks up the addresses of all the Mikhail Maximovs living in the city in the address book and sends them letters inviting them to visit her at the same time.
