The interior of a large exhibition hall is displayed. The camera pans up to showcase a banner that reads "APH MOCOBA" and "MEJDYHAPOMMAЯ BыCTABKA APXиTEKTYPы" in Russian. The hall is teeming with people exploring various booths. The hall features a multi-story building structure with a grand staircase and a clear, geometrically patterned roof supported by a complex network of metal beams. Rows of chairs are set up in a section of the hall, with people seated and facing forward.
