Orlova plays an American circus artist who, after giving birth to a black baby (played by James Lloydovich Patterson), immediately becomes a victim of racism and is forced to stay in the circus, but finds refuge, love and happiness in the USSR. Her black son is embraced by friendly Soviet people. The movie climaxes with a lullaby being sung to the baby by representatives of various Soviet ethnicities taking turns.
