Based on the fantastic story by Kir Bulychyov "Can You Ask for Nina?".
Guests gathered in Vadim Nikolayevich’s apartment to celebrate the 1979's New Year with a cheerful company. The landlord unsuccessfully tries to reach his friend Nina. He, dialing a number, gets to a girl who is also called Nina. Her answers seem strange to Vadim Nikolayevich until he realizes that he is in some unusual way talking with a child from Moscow in 1942.
