Yulia plans a loving birthday surprise for her husband Boris, but days before the celebration he suddenly leaves on a “work trip” to Kazan. On his birthday, Boris ignores Yulia’s calls. Eventually, a video call connects—and a woman named Mila answers instead.
Mila cheerfully introduces herself as Boris’s girlfriend and assumes Yulia is his sister. She reveals they’ve been together for almost a year and are celebrating his birthday together. Yulia stays calm, hides the truth, and suggests a joint birthday surprise.
When Boris comes out of the shower, the video reveals Yulia and his two daughters in party hats. The girls happily congratulate their father. Yulia then calmly shows their marriage certificate and tears it up on camera, exposing Boris’s lie to Mila.
She announces the divorce, explains that shared property will be divided, and that Boris will pay child support. Mila, shocked to learn Boris is married with children, leaves him immediately.
Yulia later files for divorce, celebrates her new beginning with friends, and moves on—while Boris is left alone, facing the consequences of his deception.
