The Rio de la Plata is the place where all music converges. It is the region where very different genres such as Tango, Rock, Candombe, Murga, Cumbia and Milonga first met, giving birth to our own unique music. Pablo Dacal, music and troubadour, sets out to find the origins of our song, meeting up with fundamental characters of the Argentinean and Uruguayan music scene. From Gustavo Santaolalla, Jorge Drexler or Fito Páez to almost unknown yet equally great artists, this film features them all in a profound look into the Rioplatense Song.
