A film maker Natalia Alamada made a life audio recordings about her great-grandfather Plutarco Elias Calles, a revolutionary general who became president of Mexico in 1924. A former primary school teacher and general of the Mexican revolution (1910-1920), Calles ruled Mexico from 1924 to 1928. One thing I observed while I watched the movie is that Alamada developed the story unexpectedly by moving the camera from one subject to another and from past to present. The most things attracted me was the unlicensed street vendors. The film begins with and returns again to the street-level realities of Mexico City including the unlicensed street vendors.
