In 1966 and 1967, Franco Cigarini takes part to the "La Fête de l'Humanité" in Paris. He will film some moments of the celebration, and will make a documentary, "La plus grande fête de France", with other images shot in 1966 - film commissioned by the Italian Communist Party "Togliatti" section in Reggio Emilia. The excerpt opens with shot inside the pavilion dedicated to the October Revolution 50th Anniverary ("Hurrah for the Soviet Youth friendship"). A few young men spend time at the "Bois de Vicennes" park (East of Paris), where the 1967 edition of "La Fête de l'Humanité" was held between September 9 and and 10.
