[1][2][3] In the film, a peculiar phone service plan called the "New Year’s Tariff" comes into play when a young man named Andrey receives it as a gift from an unusual woman while purchasing a replacement phone.
Determined to meet her, Andrey visits Alena’s address but learns she was tragically killed in a car accident just 15 minutes before New Year’s 2009.
To save her, he investigates the accident, uncovering every detail, and relays this information to Alena through a video message in her timeline.
However, their efforts fail, and in a twist, Andrey—recently back from a work trip—ends up on the bus that Alena was meant to avoid.
Andrey, stepping off the bus, is nearly struck by a tanker truck but is saved when Alena calls his name at the last second, reuniting them safely at the end of 2008.
