A parade of athletes on Red Square: columns of athletes are walking along the square with flags, demonstrating acrobatic exercises, cyclists are passing by; athletes, playing football, tennis, jumping from a tower; horsemen are passing by. Party and state leaders greet sportsmen: among them I.V. Stalin, L.M. Kaganovich, K.E. Voroshilov, A.I. Mikoyan, V.M. Molotov, writers: A. Gorky, Romain Rolland.
