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.
