Mila dreams of a new microphone to record a hit. However, her father is not ready to give her such an expensive gift until she gets a passing grade in geometry. A youth clothing manufacturer offers Mila a chance to appear in their advertisement for a substantial fee that would be enough for two microphones. Nina, Mila's loyal friend, finds this suspicious, as Mila is not yet as famous as she could be. Additionally, the filming coincides with Mila's attempt to pass her geometry exam, which means she will have to choose between her studies and her artistic pursuits.

Mila has four Ds in her quarter, and this is a serious problem. Alexander Sergeyevich doesn't even want to hear about the fact that a future singer doesn't need geometry. The principal demands that his daughter find a balance between music and her studies, or she will have to give up something. And it certainly won't be school. Mila's secret is revealed to her classmate Alina, who demands that the singer break up with Max. Otherwise, everyone will find out.
