This is a documentary film on the music of The Gaiteros of San Jacinto, of the Caribbean coast of Colombia, and on the history of cumbia, one of the most popular forms of musical expression in the Americas today. Gaitero music, which has been in danger of disappearing, is the original folkloric form of cumbia, and the root of all modern cumbia. The film is also a post-humous tribute to Antonio "Toño" Fernández, who was the first musician to put words to gaitero music.
