A video shows a stage performance of students in front of a seated audience. The stage is illuminated with red and yellow spotlights, with a screen at the back displaying the words "12 E Клас". The performers are dressed in dark clothing and wear white masks. They are engaged in a dance routine, moving in unison. The audience is seated in rows of blue chairs, and many people are holding up their phones to record the performance. The building appears to be a large auditorium with a partially covered roof.
