Seventy critics and filmmakers discuss cinema around the conflict between the artist and the observer, the creator and the critic. Between 1998 and 2007, Kléber Mendonça Filho recorded testimonies about this relationship in Brazil, the United States and Europe, based on his experience as a critic.

In 1952, Ernesto Guevara, then a medical student aged 23, and his friend Alberto Granado, a biologist of 29, began a long journey through the South American continent. During their tour, which began with an old motorcycle to continue after hitchhiking, they witnessed the harsh living conditions of the population of the countries they travelled. Guevara, soon to be known as Che, recorded his impressions in a diary. In 2002, the Brazilian director Walter Salles began shooting a film about that odyssey, "The Motorcycle Diaries". This documentary follows the making of that movie in detail, incorporating interviews with various participants.

On 17 May 1931, the young director Mário Peixoto released his masterpiece "Limite" in a premiere in Capitólio Theater in Rio de Janeiro to astonished audiences bewildered by the impressive and poetic images. Considered by many viewers the best Brazilian movie ever made, this feature has never been released commercially. However, in a great paradox, Mário Peixoto has never made any other movie. The director Sérgio Machado pays a great tribute to the life and work Mário Peixoto a.k.a. Maçarico by his close friends with this documentary, using his diary; footages of "Limite", the never concluded "Onde a Terra Acaba" (1933) and the short "O Homem do Morcego" (1980); and interesting testimonies of Olga Breno, Ruy Solberg, Nelson Pereira dos Santos and Walter Salles among others.
